@ivorycruncher: (don't like quoting long posts)
You're right, it's just an assumption of mine, but to call it "stupid" is an insult.
But nevermind that, you made certain points, which other people who claim to have used Windows 7 beta did not. I am also in IT business for a long time (since 1994) and I have seen many versions, and it was ALWAYS the same thing: people dissing newer Windows and praising old (and a year later, LAUGHING at people still using older one).
Then Vista came, culminated this trend (adding its own huge blunder that is UAC), and a year later still not getting enough praise (in my opinion, reason is not being such a leap forward like WinXp to Win98)
This though, such unanimous high opinion from beta testers - is a surprising thing, but I was (and I still am) afraid it's only a response to a "cleaner" Windows to a bit of a resource hog that is Vista.
"Snappier" response sounds good, but if I can't see more than that, it cannot make me (an older guy) waste some time and energy installing it in a moment, when there is little support for various hardware I use. Vista brought DirectX10 (sadly, supported very little by software companies), Readyboost and Aero. What Windows 7 REALLY brings us? I'm afraid it brings us nothing much, but effort to take back customers driven away by long bootup and UAC.
P.S.
I WILL try it out though, WHEN I have some spare time
