I tend to drag my heels when it comes to OS's, I get used to one, and I don't see a whole lot of benefit in upgrading. These days, well lets say, since WindowsXP - we have been forced to upgrade, for new gfx cards, for DX10,11, for memory support, for hardware issues... but really there is no real tangible improvement. My main PC is a dual boot XP and Win7, and the Win7 install is only there for gaming. All my development is still done in XP. To be honest, I'm not sure I have to change, nobody has ever given me enough justification to go full Win7. Win8, well I don't even count that as an OS, I want nothing to do with it.
Personally, I can't see Windows suffering much in the desktop market, it'll always be the top dog for desktop PC's. But for tablets, I think that Win8 will be torn a new one, by alternative OS'es like Linux. They are trying to do too much with mobile OS's these days, and Microsoft will be as bad, or worse than everyone else. People will very quickly get sick of Win8 and look for alternatives, and that's especially true now that Steam is heading for linux. I mean, these higher powered tablets, and the Razor gaming tablet thing will use the cheapest and most accessible OS available, and that's unlikely to be Win8.
Everyone wants a bit of the mobile gaming market, but there isn't even a second standard, there's iOS, and about a dozen alternatives. If those alternatives concentrated on 1 single OS, invested in it, supported it, then the marketplace might be very different by now - imagine having global software support, software that will work on better hardware as it's developed. It's like that scene from Oliver, and Microsoft is Oliver, begging Apple for 'some more', with it's hungry little tablet in it's hand

. If we look at Microsofts track record with mobile... well their MP3 player didn't last long, and nobody really uses their mobiles... for me, getting a Microsoft mobile would be like asking a charicatre artist to do my passport photo.

Health, Ammo, and bacon and eggs!
