It is gorgeous. I09ve been using it all day, and I09m definitely a big fan. Internet Explorer is a little quirky, but Mozilla is supa' dupa'. And so is AIM.
Here's my $0.02 about Apple: I think the Switch campaign is annoying and misrepresentative of Windows. In my experience, Mac OS 9 crashed just as much as Windows 9x. Mac OS 10 and Windows XP are both virtually crash-proof (thanks to protected memory and less legacy support), and they are equally usable. (That's assuming you have a two-button mouse. One button: WTF?).
So instead of just using Windows, why not use both? As an early Christmas present, how about an iBook? (Don't forget the Airport card.)
