Yeah and the fact is that there really isn't that much to upgrade anymore, in my opinion.
I think Windows 7 will surprise you and your so-called "facts."
Well, no, he's right... the basic operating system doesnt change that much, I mean it has hardly changed since Win95. If everyone went 64bit tomorrow, then theres a big change in operating system. Windows is so clogged full of shit I never use, I wish Microsoft would release a basic stripped back version of Windows. No extras. Like DOS was until they started adding little things.
That said, I have extensively used Vista, and really, it blows goats. Thats what happens when Microsoft try to out Apple Apple. I stayed with XP.
