RT is for ARM processors only (tablets). It's released to manufacturers only, you can't buy it. It only runs applications in the Windows store.
So its basically windows 8 without the actual desktop and ability to run exe files?
I'm thinking they are going to have a heck of a hard time selling that over android.
I would really like to get a windows 8 computer/tablet, but if RT has fewer features, then I can wait.
