I've been running it on my Netbook (Samsung NC-10) since the RC, and I'm loving it. Actually, it's still running the RC. I might upgrade this weekend. Initially, I wasn't too sure about the new taskbar, but I'm liking the extra features now (the Aero Peek stuff, etc.).

I'll probably rebuild Jen's Vista laptop (Samsung Q45) this weekend as well. Assuming I finish replacing my Windows 2008 box with a Linux box...
