Windows RT is not the future, Windows 8 is. The problem with Windows RT is the lack of support for legacy apps. What that does is prevent users from downloading any app released for Windows 7 and back. The only desktop apps that can run on Windows RT are Office, and System applications like Control Panel.
What this means for Windows RT is that it is restrictive. It should be something that could open up and be functional and full featured, but it feels like half of an operating system. That's because it is half of an operating system.
If there was a developer who could figure out how to get x86 apps running on Windows RT, he would be showered with money. Right now the Windows Store is small, the apps many people want aren't in there. But they are already on the desktop.
What Microsoft should have done was to push OEMs to make x86 Windows 8 tablets for a lower price to compete with the iPad instead of RT tablets. That is where the future is, open access to whatever you want. If you want to use the device as a traditional laptop, you can, if you want to use it as a tablet stay in the "metro" interface and use those apps.
Acer sees this and is waiting in the wings until 2013 before they jump into the RT tablet game; however, they do have x86 Windows 8 tablets. Acer sees what I see, a short life for Windows RT and here's why.
Windows RT restricts users choice. The x86 Windows 8 tablets open things up for users. My argument is that Microsoft has rolled out its new OS with a small pop instead of a big bang. If the Surface Tablet ran the full x86 version of Windows, like the Surface Pro will when it comes out, the excitement for Windows 8 would have been much greater.
The only way I see Microsoft going anywhere in the tablet field is to focus on x86, having OEMs work with Intel to make smaller, faster, and cheaper chips. If Intel chips can get cheap enough for an OEM to pull of a $499 price point for a full x86 tablet with the option to buy a keyboard dock, then I believe it would shake the tablet market. Apple would have to scramble to compete.
As of now, if you read my previous article on how OEMs botched the x86 tablet launch, I feel that Microsoft put money into the wrong product. In 3 years, whenever Windows 9 comes out, either the RT version will have to work with x86 applications(using some form of virtualization), or RT will be no more and there will only be one version of Windows 9. It should adapt to the devices it is installed on.
Once OEMs actually get x86 tablets and hybrids into consumers hands, I feel that the buzz about them will overshadow the Surface RT Tablet. It will most likely fade away as more full featured tablets come out.
