I have Whidbey and Framework 2.0 running and it's pretty damn slick. I'm running Yukon too (the new SQL) and it's whole new OO world at M$. Longhorn (of course) is turning out to be really exciting, especially with a fast machine that can render DX9 video and audio.
I'll get off my soapbox now, it really is some fun new technology though.
