As a current Windows user, and someone who desperately want to switch to an iMac, I just wonder whether the launch of 8 is a factor in Apple plans for new iMac launch. I'm sure the marketeers in any normal business would have their carefully crafted and cunning plan to spoil the Microsoft party ?
Against a background of very 8 capable and technically up to date Windows all in ones, would Apple be so arrogant as to not even blink about 8 ? I'd have expected they must be understanding that iMacs are in a sector that to grow market share, they need to get right ? Much of the market is waiting for 8 to prompt a new machine purchase, and some of that market are potential switchers.
Maybe I'm naive and not understanding enough of Apple culture, but to a marketeer, Windows 8 isn't just a background and insignificant distraction.
