I just looked at the comments on one of the post on dual-boot on Windows 7 and XP/Vista, it is really funny to see the comments there;

Anybody wishing to try out the beta software should know how that level of things work, well my opinion.

My experience, I got it from my work and have already turned my test machine into a dual boot machine. The install was a breeze and startup/shutdown times are pretty impressive. But I can sense high about the Vista on 7 (though 7 is an improvisation of Vista, expected something different). Haven’t yet put through all the tests that I normally like to do on a OS. But initial impression is full of ‘eye candy’ stuff and some usability enhancements which matter a lot!
