Well since this thread is about a desktop OS it certainly makes sense that the context of my post on market share was about the desktop OS marketshare.
LOL! Point taken.
I think it would be accurate to say that MS biggest hope with W8 is in the mobile market which it is lagging behind - as PC sales drop.
Any upgraded OS should replace the existing one on the same platform; the challenge MS is taking on is leverage their PC share into the phone/pad/mobile market.
Getting into the hardware business - competing with its VAR base is going to also be interesting.
