I stared using the beta version (7000) of Windows 7 in January, and used it until de RC came out.
My impression is that the beta was better.
When I saw how good W7 beta was I started hoping that Microsoft would´t ruin it in following releases, but it seems that´s what´s happening...
Just curious. I should be able to pick it up from MSDN tomorrow through work (assuming the links I've read saying it's available through MSDN/Technet are true). My boss has the account info for MSDN and he's out today so I won't be able to download until tomorrow.
I'll be reloading my desktop...
