I've been hearing mostly positive comments on Windows 7. Although I have yet to exprience the interface personally, It does look promising in a number of ways. Currently I'm sticking with Windows XP Pro on my main system and Linux Ubuntu 9.10 on my secondary system. I surely will not be paying $200-$300 for the Windows 7 upgrade since I see no need at this time. I recently read a good article on someone's exprience in upgrading from Windows Vista to Windows 7, which explains some of the pros and yes, cons, of Microsoft's new OS.
