It's also because MS refused to have existing X86 apps to run on the platform. I'm sure it was to chunnel everyone into metro of whatever they call it. They could have had a whole ecosystem by default (at least for 2d apps). But nope.

They could have implemented a wrapper around a program to allow usage. WINE already can do that with PlaysForLinux. But like I said, the hardware is spectacular; the software is a slum.
