I have used mac os x, and linux (ubuntu, badger something? about 3 years ago). And I still prefer windows over those ones.
I think Breezy Badger may have been back before I was born!

They mistakenly assume that gays are pedophiles. It's not the same thing.
No one ever says they need to ban heteros because some people molest children of the opposite sex.
Hopefully, the psychologists they hire will inform them of these (pretty obvious) facts.
Impartial psychologists? Paid by the vatican? ha!
Well, I believe that a company has the right to do what they want.
Windows XP wasn't new either, since it used (heavily) code from NT.
To be honest, my timeline with windows has been 3.11, 95, 98, 2000 (for a brief period, before going back to 98), xp, vista (on a new laptop, only for the time it took me to download windows xp), and now the beta for w7.
And I think that w7 is the best thing that has happened (in windows) since xp. And that's about 7-8 years?

And about the price, well, if it exists, it's pirated. If it hasn't been pirated, it's on its way.
And yes, I agree with ArsTechnica that vista was a HUGE mistake and a SHIT operating system. But it had good ideas. And it had terrible implementation (UAC I'm looking at you).
At least, what I've seen so far about w7 has improved those flaws, and added improvements.
Two things:
1: microsoft released the rc's and betas for previous windows, so nothing new in there.
2: it's still a beta. it might be release candidate, but it's still a beta.
Laughs its funny, but the uniform isnt correct, oh well least they tried!!!!
BUT, HOW!
my suggestion is to install the official nvidia drivers, rather than using the default.
not the last time I used it!
but let's keep this thread out of the "my OS is better than yours" 
it's reasonable to ask for a ransom for a operating system.
some people don't want to spend hours configuring a operating system
sure is not biased around here!
