We will see if Microsoft can turn it around. If Window 7 is as good as they say, it will certainly give apple a run for the money. If it sucks, it will boost Linux.
The Betacam mindset of Apple has limited the acceptance of it’s OS. Not everyone digs apple hardware.
I have W7 on both my computers. Installation was a breeze, no reinstalling of software, and my computer is faster. So far, so good.
