think of how people use tablets..you don't need full OS versions to meet those requirements. Anything else is overkill (and probably battery draining)...
Man, what is your point? I am talking about support for legacy applications, applications that won't run on a different processor architecture/instruction set (x86 vs ARM). That's the case for iOS, Windows and Mac OS. It is not, repeat, not the case for Android. Different story. Android is, to a certain point, platform agnostic.
If you're telling me that support for legacy applications is not important, then the door would be open for Intel x86 on iOS, which I believe is not. Nobody would buy an x86 based iPhone which doesn't support all of the legacy applications. And, to be once more clear here: It would require full recompilation in that case by the source code owners, which is out of reach for Apple, Microsoft and any other OS supplier. It's completely in the hand of third party suppliers (App developers).
