I'm beginning to like it now. Before, I was really against it, but I think that was also because it wouldn't let me have it dual boot with Linux. I've since got that working, and been running it for just over a month.
So far, all the software I need works fine, drivers haven't been a problem, it's installed my sound card, video card, Firewire etc. Seems to run at a reasonable speed using the Aero interface.
And I still have the advantage of running linux.
