I can see how that would be a pain (WiFi). The new box will take me at least 1~2 weeks to setup the way I like things, then I'll be able to upgrade to Vista when the final release is out.
I've heard good things about Vista RC2, but still curious to hear from others.
The new box is an Intel E6600, so it's pretty quick. So far things are looking ok but I haven't even install Visual Studio yet (or anything else for that matter).
