Not to worry. Microsoft will claim millions and millions of Windows 8 sales in the first few months. They'll crow about Windows 8 market share in enterprise, thanks to those corporate PC sales by HP, Dell, and others, with Windows 8 pre-installed. But actual usage will be far smaller. Because corporate IT departments around the world will just re-image all those PCs with XP like always. And consumers won't like Windows 8 at all. Only the most rabid Microsoft faithful among them will pay $40 to upgrade. The rest will get Windows 8 by default when their old PC freezes up and they're forced to buy a new one. And they'll hate it.
Indeed , in the case of professional world, the prescriber (the IT Department) is not the actual user (or just a tiny part of it).
Indeed again, an incredibly high number of Windows users quit accessing to Internet, just because .. it's too much trouble , too risky, and the destiny of their PCs is to die "frozen".
Companies replace their PCs when the cost of maintaining them to life exceeds the replacement cost. Consumer users replace them when they are fed up of doing the continuous clean up work (defragmenting, chasing viruses, eliminating incompatible applications , etc ...) it requires.
When Mac users replace their Mac, it is because they cannot resist to the appeal of a new one, but the old one is still functional. They keep it, most of the time, but if not, they can sell it easily on the second hand market.
What is to be pointed out, I think, is that Apple has raised the OS capabilities to an unprecedent level. It is not just discussing how easy it is to access to applications, data (although it does matter), but it is about providing the user multiple means of communication (keyboard (possibly virtual), mouse (idem), but also voice input, gestures ...
Not to mention, also, the Cloud capabilities, which enterprises will of course ban, but which be change the average consumer life.
Microsoft stuff, from this standpoint, will appear as totally obsolete.
Admitedly, this might not be a strong selling point for the prescribers in the professional world, but for the consumers, it will be a different story ...
