Well me and the missus got us a shiny new laptop (on contract cause we're poor lolz) that has Vista Premium on it, but we also got a free upgrade to Windows 7 Premium when it gets released on Oct 22nd, must say I'm quite excited!
I've tried the RC on my old laptop and I must say I like
Edit: 17" screen 1440x900 is very pretty for a laptop to watch movies n stuff on
