As a Windows RT user I am very aware of it’s short comings. Although it tries to market itself as a premium Tablet , with a price to match, it’s serious lack of applications and inability to run full windows 8 programs make it fail to live up to the hype and promises that some of the full windows 8 tablets may.
However, a hacker has been working to address at least half of that imbalance by creating a way to run full x86 applications on Windows RT tablets.
Windows RT opperates on ARM processor machines (the same processors you find in most tablets and Smartphones) and so is “incompatible” with Windows 8 programs and applications. Or at least that was the line from Microsoft when it was released.
