To a different point Unix has won the tablet war, it's down to Linux based Android and BSD based iOS. Unix installed base now is around 900 million devices. The installed base of Windows is hard to calculate because it's been around longer, how many of the 3 billion manufactured units are still in use? 1 in 3? The numbers are likely close.
Android has barely dented iOS on the
tablet front. The numbers you are referring to includes Android
phones. If one wishes to call iOS "Unix" or "BSD", and Android "Linux" that's on them. But sticking a Ferrari decal on a Honda, or vice versa - depending on your perception, is sort of wonky. Based on and actually being are two real different things, and until the day comes I can download source code for *nix and natively compile it without changes on either Android or iOS, I do see a difference.
Apple is still far more profitable despite losing quite a bit of ground market share wise to Android on the handset end. iOS developers make more than Android developers still, despite the larger market share going to Android.
PS: my daily driver devices are Android based. No Apple fanboyism here, just facts. Simple as searching for "iPad market share".
All Windows 7 games run on Windows 8 without issue, for the most part. I've not yet hit one that does not, and I purchase 5-6 a month. The claim that game manufacturers do not support Windows 8 is horseplop unless your version of "supporting Windows 8" is a giant sticker on the box that SAYS "FOR WINDOWS EIGHT!!!!11!!".
It doesn't really need to be stated. Windows 8 has a full desktop GUI that really is not terribly different than Windows 7, and around here, most of the W8 detractors are guys that will openly admit they have never even tried it
