I think Windows 8 will be interesting. The one thing I don't like about Windows, since Vista, is the splintering of the client version (basic, home, professional, ultimate). I think MS should just make one client version for a flat $150.00.
Microsoft isn't Apple. Their biggest customers aren't end users; they're large corporations with thousands of users, and PC manufacturers. Tempting end users is just marketing to them.
I actually prefer taht. It gives me a choice to pay for whatever I need to use as opposed to Apple where no matter whether I need it or not, I have to pay.
