LoganSnake, here's a great link for you, or others wondering about Windows 7 Beta:
What You Should Expect from the Windows 7 Beta :: the How-To Geek
I've been using it for only one day but I am quite impressed. Firefox 3, Chrome, work just fine. McAfee AV, which I use in XP Pro does Not work. So I am using AVG Free AV for now. The Beta will expire Aug, 09. If it wasn't for that I would probably just replace XP Pro with 7 now. But it is a Beta so I will keep Dual-booting for a while, at least. Let me know if you have any questions.
