I'm a bit limited when it comes to the RT market. What shortcomings does it offer?
All of the other responders don't want to admit that RT Can't run Windows 7 apps. It also cannot run some metro apps designed for W8.
Huh? The guy two posts above you specifically said it can't run exe programs. And what Metro Apps designed for Windows 8 can it not run??
All apps released through the Windows store run on RT or 8.
You seem to think that its a completely different OS. Its really not much different other than its compiled for a different Chipset. Legacy apps could technically be compiled for ARM processors and then work on RT.
Limitation relative to Windows 8 is that you cannot install any applications from outside of the app store (similar to an iPad).
Final question, what games that I bought on windows phone 8 can I play on my rt without buying again?
