As long as my games will run on it, and it has similar apps for my apps that don't run on it. Unfortunately, that is where MS has us by the b***s. I have a nephew that works at MS and even he thinks this back-level compatibility stuff is pure crap.
Many people think Bieber is a singer, hotseat is not needed

I guess source of problem is because people are lazy and don't do things personally, they have IT-department, who "makes their stuff works" for them. Most people just want one big button "make it cool now". When they begin to have problems on personal level, that's when concern and care appear. As long as mitrosoft is going to have casual customers who use their PCs/tablets/laptops/phones for "skype and kitten", well, you know, wall of rooms where IT-departments quarters will hear a lot of interesting curses, swearing, and obscenity.
