Most Popular Tablet PCs of June 2009

Welcome to the June 2009 Most Popular Tablet PCs list. This report is made using the total page-views each product page receives in one month; so each time someone clicks one of the product links, they are submitting a vote in our monthly rankings. This list doesn’t always show which models are the best selling, but instead the models that readers want to research the most.

This month the list stayed consistent with the previous month. There has been little change in the tablet market, but we hope with the release of the new ASUS Eee PC T91 that we see some shift in the market. We will also be receiving a Dell Latitude XT2 review unit soon, which should boost some traffic to that notebook and move it up the list.

VAIO W Netbooks sony

Just when you gave up all hope that Sony would release a netbook that costs less than $900, Sony today launched its attractive new line of netbooks--the VAIO W Series. Featuring cool colors, 10-inch screens with high-resolution, as well as a comfortable keyboard and touchpad, the VAIO W promises to make a splash for just $499.

Like all the netbooks that have come before it, the new W Series should prove to be a nice secondary PC for browsing the web from any room in your home or while you're relaxing at a coffee shop. The VAIO W will only be offered in one hardware configuration at the time of launch but comes in your choice of three colors— berry pink, sugar white and cocoa brown.

The W Series offers more screen real estate than most netbooks thanks to a high-resolution, 1366 x 768, LED backlit 10.1-inch widescreen display, making it easier to view one or even two web pages without the need for side-to-side scrolling.

The VAIO W also features an isolated keyboard which should prove easier to type on compared to many of the keyboards found on 10-inch netbooks. The VAIO W likewise has a larger touchpad and mouse keys compared to typical netbooks, so the touchpad will likely be easy to control.

As an added bonus, the VAIO W comes with VAIO Media plus Multimedia Streaming software, a media sharing application that lets you wirelessly stream content across DLNA-enabled devices throughout your home network. In other words, you can wirelessly send video, music and pictures from the VAIO W to your compatible primary PC or PLAYSTATION3 and vice-versa.

The list of standard features also includes two USB ports, built-in Bluetooth for connecting to wireless peripherals, a built-in webcam and microphone for video chats, and a standard 160GB hard drive for storing all your photos, files and videos. The VAIO W comes Microsoft Windows XP Home Edition operating system, so this netbook should actually provide better performance than the more expensive Sony VAIO P running Windows Vista.

The VAIO W Series netbook will retail for about $500. It is available for pre-orders today online at the Sony Style website. It will also be sold at Sony Style stores and at other major retailers around the country starting in August.

Acer Aspire One

Product Description:

The easy-to-use Aspire One netbook with 10.1” display provides continuous access to the Internet and weighs just under three pounds.

The Aspire One comes with the Intel Atom processor, built with the world's smallest transistors and designed specifically for low power consumption while delivering the power and performance you need for full online freedom. The Acer Aspire One comes standard with a 6 cell battery pack offering an oustanding 7 hours to enjoy your Aspire One in complete freedom.

Measuring just 10.2 x 7.2 x 1.0 inches it's smaller than an average diary and at 2.9 lbs, it will slip so easily into a bag or backpack you'll hardly notice you have it with you. Make no mistake; this is one of the smallest, lightest, and most individual ways to carry freedom with you. Freedom to use WiFi to explore new ways to connect, communicate and interact with the world you care about.

The Aspire One has an 10.1" CrystalBrite LED backlit LCD display with a resolution of 1024x600 pixels which makes it a perfect fit for the most user-friendly interface available."

If you find you've run out of storage space, the Aspire One has another ingenious solution: Smart File Manager instantly and seamlessly merges extra storage capacity from any SD card inserted in the 2nd card slot into the main memory available to the user, so you're never short of storage space.


Windows Vista brought with it DirectX 10, and with DirectX 10 came a completely new approach to handling shaders. Gone are the distinct pixel and vertex shaders, replaced by unified shader technology that's much more flexible.

With each GPU I'll be noting the number of unified shaders in that part, but I want to make clear that Nvidia and ATI use completely different approaches to their shader designs. For example, Nvidia's top end part on the desktop has 240 unified shaders, while ATI's has a staggering 800. If you look at the raw numbers, the ATI part should be monumentally faster, but the designs of the shaders are actually radically different and as a result, Nvidia's top end outperforms ATI's. Thus, the number of shaders should only be used to compare same-branded parts and not ATI vs. Nvidia.

More is, of course, better, but will also draw more power and throw more heat.


One thing that hasn't really changed much in the time past is memory bus technology. In general, you will see three different memory bus widths on mobile parts: 64-bit, 128-bit, and 256-bit. Parts worth gaming on will generally never have a 64-bit memory bus, which is the thinnest and slowest. A 256-bit bus, on the other hand, is much more expensive to produce and so will only appear on absolute top end cards. The happy medium is often a 128-bit bus.

There are also four types of memory in circulation for mobile graphics. The first three differ generally in the top speed they can run at, while the fourth is newer and very different from its predecessors.

These first three are, in order of performance capacity, DDR2, DDR3, and GDDR3. Many manufacturers will mix up “DDR3” and “GDDR3,” and for the most part that's okay as they'll have pretty similar performance characteristics. DDR2 is the slowest by a mile and on most parts is going to be the second biggest performance bottleneck, next to the memory bus width. If you're going to be gaming, you'll really want to avoid DDR2 if possible.

The fourth and still somewhat rarefied memory technology is GDDR5. GDDR5 actually runs at a quadruple data rate instead of double like the other memory technologies, and can produce mountains of bandwidth. The use of GDDR5 almost effectively works as a jump in memory bus width. GDDR5 used on a 128-bit bus can produce memory bandwidth comparable to a 256-bit bus, and on a 256-bit bus can produce staggering bandwidth comparable to a 512-bit bus! As someone who actually has a desktop card using GDDR5, I can say it works pretty much as advertised; when tweaking the clock speeds on my graphics card, the memory speed is almost never the bottleneck.


Outside of the new G200 lineup that Nvidia has recently announced, mobile GPUs are always cherry-picked desktop GPUs. It's the exact same silicon with tweaked clock speeds. As a result, each mobile part has a desktop analogue that it can be compared to. Since reviews of mobile graphics are so rarefied (I try to do my share but it doesn't seem like enough of them ever pass through my hands), it can be helpful to be able to search for a desktop part and at least get a ballpark figure of how the mobile part you're looking at will run.


One of the big differences between ATI and Nvidia right now are the technologies they're pushing to compete with one another. ATI has been the only vendor up until this point (the point of Nvidia's announced G200 parts) that produces DirectX 10.1 (as introduced in Windows Vista SP1) compatible parts. DirectX 10.1 support has been fairly rarefied, with the most notable introduction so far having been Ubisoft's Assassin's Creed. If you're looking to buy that particular game, do not buy the Steam version. Instead, buy a retail copy and do NOT patch it. Ubisoft removed DirectX 10.1 support they claimed was buggy (it wasn't) in a patch, and with that support in place, ATI cards have a massive performance advantage against the competition. Outside of this instance, DirectX 10.1 hasn't been terribly relevant.

But then again, neither has PhysX. On-chip PhysX is only usable on Nvidia's higher end parts, and can add additional detail to games that support it, like realistic cloth, breaking glass, etc. Unfortunately, like DirectX 10.1, PhysX hasn't proved remarkably compelling either, with the only notable title using PhysX hardware acceleration being the game Mirror's Edge.

Alongside PhysX in the Nvidia corner is CUDA, which is Nvidia's general purpose GPU computing platform. CUDA is seeing decent support and may be of interest to videophiles, where GPU-accelerated video encoding can produce healthy performance gains in CUDA-enabled applications. That said, I edit video on my desktop and have yet to have seen a need for a CUDA-enabled application. More than that, CUDA's shelf life may not be that long with the OpenCL standard beginning to surface. OpenCL is similar to CUDA, except that it's platform-independent. I can't imagine developers playing the vendor lock-in game and only using CUDA when OpenCL (and even Microsoft's upcoming DirectX 11 Compute Shaders) can run on either company's GPUs.

These are things to be aware of, but they shouldn't affect your decision.


This, on the other hand, probably should impact your decision process. As much as I have a stated preference for ATI's hardware, they're woefully behind on the front of providing unified mobile drivers. The Nvidia user is going to be able to update his or her video drivers with new releases (meaning new fixes and performance improvements) just by visiting Nvidia's site and downloading new ones. ATI users aren't so fortunate; if they want to update their drivers they have to either rely on the notebook manufacturer to update (good luck with that) or use third party software to modify desktop drivers (a chore).

I don't have too much of a problem doing the latter, but it can be a real headache for the more novice users, and for that reason I would tend toward recommending Nvidia's mobile hardware for the time being until ATI can pick up the slack and make mobile drivers available on the ATI website.


Both ATI and Nvidia have multi-GPU solutions for notebooks that will, with two exceptions, only appear in massive desktop replacement units. ATI's is called Crossfire; Nvidia's is called SLI. Please note that these solutions typically don't bring a linear performance improvement; two GeForce GTX 280Ms aren't going to run twice as fast as one, as latency and driver optimization come into play. With this technology, the aforementioned driver situation becomes more important ... because if a game isn't properly profiled by the vendor in question the game won't reap the benefits of SLI or Crossfire.

Now, those two exceptions: ATI and Nvidia both have integrated graphics parts that, when combined with a low-end discrete part, can be used in Crossfire/SLI and thus improve performance substantially. These solutions are still nowhere near as good as mid-range and higher options, but they're also economical and good for battery life. Nvidia's solution with the GeForce 9400M, in particular, can also swap between a mid or high-end discrete part to the IGP when the notebook is running on the battery, resulting in substantial power savings.


Planning to play cutting edge 3D games? Excellent! Don't buy anything using Intel graphics. Intel's integrated graphics performance is historically poor and rife with compatibility issues. When you're looking between Intel parts, you're really only dealing with levels of unplayability.


In addition to being miserable for gaming, Intel's parts outside of the 4500MHD are also the only ones in the lineup (excepting ATI's Radeon X1200 integrated graphics series) that don't support high definition video decoding and acceleration. All other parts are designed to offload high definition video playback from the main processor to the GPU.


Finally, I'd just like to thumb my nose at all three graphics vendors (ATI, Nvidia, and Intel) for their complete lack of consumer-oriented business practices. ATI's mobile graphics driver situation is a nightmare; miles behind Nvidia's driver support. ATI's marketing department isn't doing them any favors either; Nvidia routinely works with game developers to make sure games run well on their hardware, and their “The Way It's Meant to be Played” program is everywhere. Whether Nvidia pays developers to cripple games or not (see the Assassin's Creed controversy), ATI's not out there hustling.

Intel's driver situation is, if at all possible, substantially worse than ATI's. I'm fairly certain their graphics driver team is either one over-caffeinated teenager in a basement somewhere, or a bunch of programmers that weren't good enough to code for Creative (at least two readers should laugh at this one). Intel has basic compatibility issues with games, and they've made promises about basic performance in their hardware that they have failed to keep. Marketing lies, but Intel's integrated graphics are still essentially broken as far as I'm concerned.

Finally, whomever is responsible for Nvidia's mobile graphics branding needs to suffer at the hands of angry consumers ... or just be fired. It's not bad enough that the market is over-saturated with mobile parts that are essentially the same but named differently, but the brands of their mobile parts almost never line up with their desktop ones. The most egregious offenders are the GTX 280M and 260M, which are actually just G92 silicon -- in other words, these are not mobile versions of the desktop GTX 280M and 260M, which are worlds more powerful.

Laptop Graphics Guide 2009

And so it begins ... after the long hiatus, the Notebook Review Mobile GPU Guide's 2009 Edition is rushed out of the gates before Nvidia can make matters more complicated with more GPUs. I have to be honest, part of the reason you didn't see this article sooner is because, simply put, Nvidia created “brand spaghetti” in the marketplace. Despite their mobile parts only being based on a couple different chips, they have a full twenty-five (25!) parts in circulation right now, and that's not including the recently announced G200 line which I'll talk about in brief towards the end. ATI's not doing too much better at twenty variants circulating, but their parts are far easier to keep track of and much easier to describe.

Because of the radical changes to the graphics market since my last guide, I have to revamp my approach to notebook Graphics Processing Units (GPUs). Pipelines and all that garbage are past tense now, with almost all mobile parts now using the unified shaders that DirectX 10 mandated in Windows Vista. And because of the product flood in the notebook market, I'm going to take a different approach and instead organize mobile graphics cards by the chips that power them. Especially when you hang out in the Nvidia sections you'll see exactly how practical this approach is.

Finally, before you get into this guide you may want to have a look at my “How it Works” entry on mobile graphics.


You cannot. Stop posting in the forums. Stop asking about this. You just can't. Moving on.

First, we'll create an MDI type of application:

Here are the steps:

1. Create a new MDI application. You can even use the MDI Application wizard (File - New - Other - Projects - MDI Application).
2. Make sure FormStyle property of the main form is set to fsMDIForm.
3. Add a main menu to the application. Let it have one item - the one that loads the MDI child from the Package.

MDI module parent
4. Make sure you build the application using run-time packages. Go to Project-Options, select the Packages tab, and check the "Build with run-time packages". You should at least use the rtl and the vcl package.

Project-Options - built with packages

Before writing some actual Delphi code, let's first build the package and add one MDI child form to it.

1. Start by creating a run-time package.
2. Add a TForm object to the package. Make sure FormStyle property is set to fsMDIChild.
3. Add one exported procedure to create an instance of the child form:

procedure TPackageMDIChildForm.FormClose
(Sender: TObject;
var Action: TCloseAction);
//since this is an MDI child, make sure
//it gets closed when the user
//clicks the x button.
Action := caFree;

procedure ExecuteChild;

//NOTE!! The export name


Going back to the MDI host application...

Here's the entire code in the main MDI form:

//signature of the "ExecuteChild"
//procedure from the Package
TExecuteChild = procedure;

TMainForm = class(TForm)
PackageModule : HModule;
ExecuteChild : TExecuteChild;
procedure PackageLoad;

MainForm: TMainForm;

{$R *.dfm}

procedure TMainForm.PackageLoad;
//try loading the package
//(let's presume it's in the same
//folder, where the main app. exe is)
PackageModule := LoadPackage('MDIPackage.bpl');

//if loaded, try locating
//the ExecuteChild procedure
if PackageModule <> 0 then
@ExecuteChild := GetProcAddress(PackageModule,
//display an error message if we fail
ShowMessage ('Package not found');

//menu click
procedure TMainForm.mnuCallFromDLLClick
(Sender: TObject);
//lazzy load package
if PackageModule = 0 then PackageLoad;

//if the ExecuteChild procedure
//was found in the package, call it
if Assigned(ExecuteChild) then ExecuteChild;

procedure TMainForm.FormDestroy(Sender: TObject);
//if the package was loaded,
//make sure to free the resources
if PackageModule <> 0 then

The above code, dynamically loads (PackageLoad procedure) the package as needed (when menu item is selected) and unloads the package when the application terminates. If you need help with the code, check the "Dynamic Form in Dynamic Package" article.

Finally, at run time, we have an MDI child form loaded from a package and working happily inside an MDI parent form:

Packaged MDI Child form inside an MDI parent

One final note: when modularizing applications using run-time packages, you have to redistribute the required packages along with the application's exe file.

That's it! As simple as it can be.

optical sensor LCD pad on notebook PC

Sharp Corp on Tuesday said it will release a new notebook PC employing an optical sensor LCD for the touchpad. Its new touch-sensing recognition method allows handwritten input and intuitive direct-touch operation. The notebook will cost around 80,000 yen and go on sale in late May.
The 4-inch optical sensor LCD pad in this notebook PC is more than just a conventional track pad thanks to its new touch-sensing recognition method: in addition to conventional mouse operation, it allows pen-based input of drawings and text, as well as multiple-finger-touch operation (gestures) to enlarge, shrink, or rotate items on the screen. For example, users can sign their name to an on-screen photo before emailing it, or they can use two fingers to zoom in and out of Internet Web sites to make them just the right size for viewing. Unlike regular touch panels, Sharp’s optical sensor LCD pad requires no touch sensor or protective film, so illustrations and photos are crystal clear. And the large effective operation area allows for more freedom of movement.
In the future, Sharp will expand the possibilities for its notebook PCs by developing software that makes the most of the optical sensor LCD pad
