Yep I did it. I re-formatted my drive and installed the full version of Windows 7 Beta, not the upgrade.... I was having a few problems with buggy software and too many restores.......I had a whole list of problems of which all except one has been resolved, and that may be a problem with a website I'm trying to access with IE 8. So far the fresh install has been running great. Very solid, and responsive. So we'll see how it goes.
