Differentiate Laptop Hard Drives

 

Laptop hard drives don’t spin as fast as their desktop counterparts, and this is down to the need to limit power consumption. However, it’s only when you take on intensive multimedia work and the likes of high-end games that you’ll really notice any kind of difference in everyday use HP F4809A. Do note, though, that you can get portable machines with drives that spin at 4,200rpm and 5,400rpm, and if you must get optimal performance, then it’s the latter you should opt for. You may end up paying extra for something that doesn’t make an awful lot of difference, though.

As for capacity, this - as you’d expect - is led by what you actually want to do with the machine. If it’s a simple, robust office and Internet computer you’re after, then you could be fine with just a 20GB hard drive, although you may opt for 40GB as the price difference isn’t too much. Only if you’re looking at heavy multimedia work or gaming should you really look much higher, and 80GB units aren’t too costly Compaq Evo N610C Battery.

The majority of portable machines rely on graphics technology that’s fully integrated into the laptop’s motherboard. Thus, while they’re fine for office applications, DVD playback and suchlike, they struggle when it comes to gaming PB992A.

That’s why graphics giants ATI and nVidia have invested so heavily in providing portable versions of their powerful desktop graphics technology. Their products, in terms of power, lag a generation behind their desktop counterparts, but for the vast majority of modern games Pavilion ZV5000 Battery, that’s not going to cause too many problems ,although clearly it’s a lot more difficult - yet not always impossible - to upgrade laptop graphics boards further down the line.

Interesting A81, 7” Tablet from Witstech. Cortex.

Interesting A81, 7” Tablet from Witstech. Cortex. Capacitive. Coming with Android? (Updated with video)

Reported by Techfresh nearly a month ago is early information on a 7” ARM-based tablet from Witstech. The A81. I have a feeling that the ‘WinCE’ specification put a lot of people off but it might be worth taking a closer look as it supposedly has a capacitive touchscreen and runs on an unspecified ARM Cortex A8 core and VGP-BPS8.

There’s also talk about $200-$250 prices and an upcoming Android build.

We had a lot of fun with the ARM11-based Smart Devices Q7 but with the bump in processor power, this would be a lot more useful, especially if WITs can get an Android build together for it and PA3399U-2BRS, Toshiba PA3400U-1BRS.

Specifications (taken from this PDF) are in the database now.

P.S. I know what you’re thinking – 1024×600 would be awesome! (Although Android on 800×480 should be quite enjoyable in my opinion.)

Update: This product seems to be availeble as the Wirelession W1060. Someone in the MobileRead forums already has one of laptop battery Digital Camera battery.

Nec VersaPro VS-7, the Ultimate Netbook is Japanese.

Before going any further with our quick review of NEC’s latest VersaPro Netbook, I’d like to stress I have no interest whatsoever in Netbooks for Dell Inspiron 1300 battery,Dell Inspiron B130 battery. Today’s Netbooks are too thick and heavy to even be considered portable… And in Japan for a couple of bucks more you can get a Core 2 Duo capable PC with pretty much the same shape, size, and weight that provides WAY more potential than the average Netbook.

That said… I admit today for the first time Netbook trends have begun. I finally fell in love with one, behold the Nec VersaPro VS-7, an Atom powered Netbook that for once gives real meaning to the term ultra portability and powered with Apple Powerbook G4 battery Powerbook G4 12 battery Powerbook G4 17 battery.

The NEC VersaPro VS-7 is one of a kind with impressive numbers
- Intel Atom Z540 (1.84GHz)
- 64GB of SSD
- 15.8mm Thick
- 725g
- A body that resists pressures up to 150kg!

Granted the NEC VersaPro VS-7 is expensive, and costs twice as much as the average Netbook in Japan, but look again at the specifications… What other Netbooks are capable of matching these amazing numbers… Seriously, 725g and 15.8mm thick. Who can beat it? I think Sony  VGP-BPS2C VGP-BPS2 VGP-BPS5 can do this.

Not only is the VersaPro VS-7 is freaking light, slim, and robust, I’m amazed by its performance despite NEC’s choice of integrating an Intel GMA500 Video chipset… We all know GMA500 Netbooks don’t keep pace when it comes to watching high quality video or even HD video files… But the VersaPro VS-7 doesn’t care what format we feed it with Laptop battery. Once installed with the CCCP Codec, whatever file we gave the VersaPro played them… Even our 720p DivX video played JUST fine in full screen… Something that we never succeed on a Vaio P. Granted the Vaio P is powered by Vista, but once Vista installed on the VersaPro we did the same test with the same results. Flawless 720/30p DivX HD full screen playback!

Built for a more professional approach, the VersaPro VS-7 may often be used with office oriented tools, like Microsoft Office… And I even took the time to install PhotoShop CS3 with Bridge on this baby, just to be stunned to see that the little VersaPro VS-7 performed as well as my Vaio G2 with its 1.2GHz Core 2 Duo and 2GB of RAM… Yep, you are reading this right, the Nec VersaPro VS-7 Netbook, that costs twiceas less as a Vaio G2 is capable of handling photos under bridge and PhotoShop CS3 as well as the Sony PA3331U-1BRS Satellite A10 battery VGP-BPS3! Unbelievable!
Conclusion:
Ultra compact, ultra light and powerful, the VersaPro for the first time is a computer I love to carry around with me and does exactly what I need when I work on the go. Sure the VersaPro is bit expensive and only available in Japan, but the difference in price is REALLY worth your consideration if you’re looking for a business tool as Pavilion dv4000 battery inspiron 5150 battery Inspiron E1705 battery… As for basic Email and Web surfing I even think the Versa-Pro is an amazing Netbook, I’d recommend it to anyone whose thinking of investing in either an iPod Touch or iPhone since it will give you exactly what you need and fits in your pocket.

Acer Aspire one A150-Aw

 

The recent Display Search Report reported that almost 70% netbook market share are carved up two brand. Acer Aspire One account for 38.3%, Asus Eee PC account for 30.3%, HP Mini account for 5.8%, takes third place, and Wind account for 5.7%, in forth place.

When Acer introduce low price 10.2 inch Acer Aspire One, we have enough reason to give more expectation to it’s market performance. So, what is the difference between 8.9 inch Aspire One A150 and Aspire One D150? Let us introduce them for you as following:

Dimension weight and optional color

This time, the Aspire One we evaluate is 10.2 inch netbook, he body dimension is 26.0 × 18.5 × 3.4 cm, the old model 8.9 inch A150 is 24.9 × 17.0 × 2.9 cm, cubage increased around 33%. But compared to mainstream 12.1 inch laptop, it reduced about 30%, so this product also with excellent portability. Even though it can’t foist into your trousers pocket same as Sony VAIO P, it is quite easy to put into your attache case.

According to the actual weight, we can see that 10.2 inch Aspire One complete machine weight is 1.182 KG, add the power adaptor the travelling weight is 1.488 KG. But the previous 8.9 inch A150 is 0.981 KG and 1.308 KG respectively. From this, we can find that 10.2 inch Aspire One increased around 20% in the complete machine side.

Same as many other brand netbook, Acer Aspire One D150 also provide a lot of color for consumers to choose, because of it’s appearance design is similar with Aspire series bijou netbook, so the two models looks like blue bijou and red bijou, besides, black shell and silver palm bracket suit for those mature business person.

Material/Screen/WebCam

Same as other netbooks, Aspire One D150 also adopt the common ABS engineer plastic as main body material, meanwhile, add a film silkscreen forwarding clarity coat on the coping surface, in the one hand, it can reflect the light better to makes the netbook looks glossy. In the other hand,it can protect the painting and pattern not be worn. But this coating is easy to leave finger mark and difficult to clean.

10 inch Acer Aspire One D150 netbook

This netbook introduce 10.2 inch LED backlight screen,the ratio between length and width is 16:9, the optimization dpi is 1024×600, hense, the presenting words is bigger and looks more comfortbale. If you hope to present 1024×768 or higher dpi, you can settle it on desktop.

Screen upside install a webcam inside and the actual shoot effection

Int the process of evaluting, we find that this netbook screen presenting effection is quite satisfied, the brightness is very high makes the users can see the screen cotent when under violent light circumstance. Besides, the webcam shoot effection is very good, color reversion is very precise.

Body left & right side interface

Netbook as a application tool, the performance demand is not very strict, the extension ability is more important, this 10.2 inch Acer Aspire One D150 offer 3 USB 2.0 interface, one is in the left, the others is in the back of the machine.

Except for the necessary power adaptor, earphone and network cable, it also provide VGA interface which convenient users to convert the menu to big screen display or projection, in addition, it also collocate a multiple card reader insert groove, it can support including SD, xD, MS Pro and MMC multi-memory card.

Wireless swith, inside construction

Many people who have laptop already but still want to buy a netbook, because they take a fancy that this netbook can surf in the internet anywhere as long as with WiFi, hence, we hope that netbook can provide more humanity design in this field. It it glad that Aspire One considered this point, it devise a wireless network switch, only need a dial then can finish all the acess and exit operation.

Hardware facility and performance test

At present, every brand of netbook even with different style, but their hardware collocation are almost the same. Acer Aspire One D150 is no exception, it introduce Intel Atom N270 processor (1.6GHz),945GSE chip group integrate GMA950 pattern chip, 1GB memory and 160GB hard disk, Atheros 802.11b/g wireless module.

Intel Atom N270 Processor detail parameter

HD Tach Hard disk average read speed:51.2MB/Second

From the PCMark05 test result, compare to the same price common laptop, netbook have big gap to laptop about the performance, especial in the processor and pattern chips section, the netbook can not suit to make video, 3D drawing and other complex tasks. But it’s memory and hard disk performance are very good, the hard disk read speec is almost same with popular laptops.

Heat dissipation and battery duration test

Next is the focused heat dissipation test, in 26℃ indoors condiction, we keep Aspire One running PCMark05 and makes it in high loading condition, two hours later, use Infrared temperature appliance to test the top temperature,normally, the palm tray section lower than 37℃, machine back lower than 42℃ will meet our satisfaction.

Now is the battery duratio time test, this time, the Aspire One we evaluated, we collocate 11.1V 2200mAh 3 cell battery, capacity is around 23Wh, besides, it has 2 sorts 6 cell for you to choose, they are 4400mAh and 5200mAh respectively.

Under the condition of standard 3 cell battery, this netbook stll able to run 3 hours, it seems like that the low collocation can’t bring low consumption and power saving advantages. If you don’t want to take adaptor when go out for a whole day, it is better for you to choose a 6 cell battery.

Summerise:

After long time probation, we understand more about this 10 inch Acer Aspire One D150 netbook, compare to the peer product, it is in leading position in comestic design, detail workmanship, and hardware facility.

Advantage: Performance is good, beautiful apperance, steady workmanship, keyboard with good elasticity

Disadvantage: Touch panel is small, hard sledding for left and right key-press, easy to leave finger mark on coping

The Ultimate Netbook 2

Keyboard & Mouse

Going hand in hand with the design are the primary input devices, the keyboard and mouse. If you’re looking for an example of a great keyboard then the HP 2133 Mini-Note PC is again our first port of call, but the MSI Wind is an equally good example.

8872-7662img3889s22

Important things to note here are the size and proportion of the keys themselves, as well as depth of travel and response. We don’t need ThinkPad X300 levels of quality here, but in this day and age it shouldn’t be that hard. Other things to avoid include putting the Shift keys in stupid places (ala Eee PCs) and poorly placed cursor keys (Eee PCs again). In fact, just avoid Eee PC keyboards altogether!

8872-7391img3365s1

As for the mouse, why on earth has no-one opted for a track point yet? It seems the obvious solution for a small machine like a netbook, since they’re easy to use and create more space for that roomy keyboard we all desire.

Screen

Screen size and resolution is a tricky one. To my mind nine inches is the sweet spot form factor wise, it is part of the reason I still love the Eee PC 901 so much despite its suspect keyboard. However, though I’ve welcomed the 1,024 x 600 resolution, if we could push this closer to 1,280 x 800 then I’d be even happier - the HP Mini-Note is the model here yet again! Another key point here is no glossy finishes! We all want to use these things outside, so we can’t have everything reflecting back at us when we’re out and about.

8872-7892eepcimage22

One other issue to consider here is: do we want touchscreens? Once upon a time Eee PCs were touted to be having them, but that seems to have fallen by the wayside and I fully understand why. As the iPhone demonstrated, if you want a touchscreen device to work it needs the interface to match and this means a lot of work. Moreover, touchscreens are more the realm of your budding MID (Mobile Internet Device) than a netbook.

Processor & Memory

Memory is pretty straightforward, though power users might desire 2GBs of RAM, at the moment at least there’s little reason to need more than the 1GB that’s the standard at the moment. Processors, on the other hand, are less straightforward. Despite the Intel Atom CPU being more or less the de facto netbook CPU, that’s largely because it’s the only one readily available at the moment. Many have touted the potential of the VIA Nano platform and Edward was suitably impressed when he took a look at it, but what we’ve yet to see is a netbook class version of the Nano and given Intel’s stranglehold on the market, it might take a while.

8872-intelatom1

So, sticking with Atom for the moment, the other issue is: do we need dual-core? Ideally I’d say yes, but things aren’t as simple as that. First, Intel has stated that dual-core Atoms are meant for nettops, not netbooks; secondly, what impact would a dual-core Atom in a small netbook have on thermal performance and battery life? Bearing these as yet untested concerns in mind the Atom N270 remains the logical choice and for the moment it does the job just fine and if someone shows dual-core Atom can work in a netbook, then all the better.

Graphics & Sound

Keep it simple! Do I need to play games? No. Do I need to decode 720p video? No. Do I need to decode 1080p video? Definitely not! All I really need is something that’ll ouput to an external screen at 1,920 x 1,200 or less, while making sure everything displays smoothly and without fuss.

8872-6086crysis51

As for sound, the Eee PCs have led the way here with some very good integrated speakers. This is great but if some money can be saved here to spend on something more important, so be it!

Storage

While we’ve seen plenty of netbooks with mechanical drives, I’m pretty adamant that solid state storage, generally in the form of flash memory as opposed to an actual SSD, is the netbook ideal. Though some might lament the limited capacity, the lack of moving parts and minimal heat produced by flash memory means better battery life and cooler running - two fundamentals for any ultra-portable laptop. Moreover, solid state memory takes up less space, so helps keep the chassis as small, light and portable as possible.

8872-7892eepcimage21
How much do you need? Well, I found the 20GB found in the Linux version of the Eee PC 901 to be more than sufficient, but I’d go further and say that internally 16GB is all you really need. This is more than enough for an operating system, all relevant programs and plenty of files and odds and sods. I’d then take an innovation used on the Acer Aspire One, adding a dedicated SDHC card reader that merges seamlessly with the internal memory. This, combined with a USB external drive and a regular multi-card reader, should ensure plenty of flexibility.

Connections & Networking

For the most part there’s very little I’d add to most netbooks when it comes to connections. Three USB ports, VGA, Ethernet, headphone and microphone jacks and a memory card reader are pretty sufficient for the usage. My only other desire would be for HDMI, since it makes playing video on a TV that bit easier.

8872-hdmilogo1

As for networking, despite Apple’s best efforts you still need wired Ethernet - so that’s a given. For Wi-Fi I’d happily settle for 802.11b/g instead of Wireless-N if it meant saving a few bob, though if I were offered N I’d happily take that, too. Bluetooth, however, is an absolute must. There was something else, too, but I can’t quite remember what it was just now…

Operating System & Software

Windows XP or Linux? If the latter, what kind? There are a few potential solutions:

1. Windows XP - Unlike its much maligned successor, Windows XP is a mature, fast and familiar operating system that already works very well. People like it, there are thousands of freely available applications for it and it has vast hardware compatibility. This makes it a safe choice.

8872-xplogo1

2. Linux - Since the beginning netbooks and Linux have been together, yet of late Windows XP seems to have garnered a foothold in the market as people demand more flexibility. What is needed, then, is a Linux OS that has the ease of use of current distros (ala Eee PC/Acer Aspire One) but with a little more freedom. A potential answer is the extremely promising Ubuntu Netbook Remix, but until it’s more widely used it’s hard to come to a conclusion. Most vitally, however, what is needed is an iPhone Application Store type platform so that users can add new programs quickly and easily, without recourse to the often tortuous installation processes used in Linux.

3. Both - Then there’s the compromise solution of Windows XP with a small instant boot Linux element available as well. This may well tick many people’s boxes in terms of flexibility and knowing Asus’ use of this technique in the past, one can reasonably expect it to do something similar in future netbooks and for others to follow.

8872-ubuntusmall1

So, what about my Ultimate Netbook? Well, logical though the final solution is my heart says Linux only is the way to go. It is, after all, the original netbook OS. What we need, however, is as suggested before, a development community and platform into which many weird and wonderful applications can proliferate. Applications designed specifically with netbooks in mind and with easy one-click installations. And if not Ubuntu Netbook Remix, is there a place for a Google Android for netbooks? I’ll leave that one up to you…

Battery

This is a no brainer. One of the abiding advantages Eee PCs have had of late is the use of six-cell batteries, when all others have relied on just three-cells and four-cells. Having a six-cell battery more or less guarantees, at the very least, four hours of battery life and with prudent use this can go as high as six, seven and allegedly eight hours, too. This is the kind of battery life an ultimate netbook needs, so six-cells is the way to go. Here i suggest netbook users for battery choosing should select high-class laptop battery manufacturer.

Size & Weight

A nine inch screen settles the size aspect fairly simply, so then there’s weight. Having a six-cell battery probably rules out a sub-1kg figure, but as close to this figure as possible should always be the aim and less than 1.3kg the minimum requirement.

Price

This, of course, will always vary depending on region, but for the UK £350 or less is the benchmark. In an ideal world I’d say less than £300, but if you want the best netbook possible, you’re probably going to have to pay a little more.

Oh, yes, now I remember what that other thing was…

HSDPA. Integrated. Please.

This is the one thing everyone is likely to agree on. If netbooks are to truly break free from the constraints of the home, the Internet Cafe or other Wi-Fi covered location, then 3G networking is an absolute must. In fact, I’d go as far as to say a netbook without 3G HSDPA should take its “netbook” credentials with a pinch of salt. If that means purchasing a netbook with a contract then I’m cool with it, but the option to go “unlocked” should always be there.

8872-blurryquestion1
To summarise , the recipe for the Ultimate Netbook, by Andy Vandervell:

  • Take HP Mini-Note and Sony VAIO TZ. Mix thoroughly and season with colourings to taste.
  • Add track point mouse to make room for well proportioned keyboard.
  • Add nine inch screen with 1,280 x 800 resolution.
  • Insert 1GB RAM module and Intel Atom CPU. Sprinkle lightly with graphics and sound that do the job, but move on quickly or netbook will become bloated and expensive!
  • Add solid state memory for storage and expandable memory options to taste.
  • Throw in basics like USB ports, then add HDMI port and whisk for five minutes.
  • Add Wi-Fi and Bluetooth modules, but don’t forget Ethernet too!
  • Install custom Linux OS and create community and development to help make it thrive. Ensure all essential software and codecs are pre-installed.
  • Insert six-cell battery to avoid premature deflation, but ensure netbook remains light and fluffy.
  • Add the magic ingredient, HSDPA.
  • Bake for three months, slowly increasing temperature through a prolonged campaign of deliberately leaked blurry products shot and proposed spec sheets.
  • Finally, release and sell for less than £350.

The Ultimate Netbook? Done.

The Ultimate Netbook Review 1

How to solve a problem like the netbook? To my mind, despite nearly every manufacturer taking a stab at the thing, none has yet quite distilled my idea of what the Ultimate Netbook would be. This is partly because, until recently, not everyone had a clear understanding of what a netbook was meant to do but also because manufacturers have all been far too busy jostling for market share to put a lot of thought into the finer details.

This isn’t to say there haven’t been some fine examples, mind; the likes of the Asus Eee PC 901, Eee PC 1000H, MSI Wind (as the Advent 4211) and Acer Aspire One have all been worthy of awards in the past, and there are plenty of new contenders from Dell, Samsung, Toshiba, Lenovo and the like that could yet fit our perfect mould. Right here and now, though, we’re still waiting.

So, if you’ll forgive the analogy, we’re still waiting for the Apple iPhone of netbooks - the example that blows all out of the water and sets a new benchmark for all to follow. Now, having looked at so many of them in the past, I’m going to try and find the recipe for my Ultimate Netbook and hopefully some of you will agree and maybe add a few thoughts of your own, too!

Design

This is probably the one area where netbooks could do with a lot more work. Nice though the likes of the Eee PC 901 or MSI Wind are, none but a select few netbooks have that look and feel that says they’re a serious bits of technology. They are, to quote an oft used phrase: “toy-like”. There is an exception, however; the wonderfully flawed HP 2133 Mini-Note PC. This is largely because, rightly or wrongly, it was meant for the business and education market and had a suitably smart but also durable design to match.

It is clearly an excellent starting point, yet its metal finish undoubtedly added too much cost. So, what we really need is a balance between this and something like a Sony VAIO TZ. Something that isn’t finished in cheap white or black plastic, but has a few more subtle curves and a slightly more quality feel to it. What we really need is a “business class” netbook, a device you’d happily sit down and use around all those snooty business execs. Something they’ll think looks premium and exclusive, but is in fact cheap and cheerful so you can laugh inwardly and say “if only they knew!”
