I beta tested this for a while, and it was horrible. Slow, no drivers, etc. Well a few days ago i got a copy of Ultimate 32bit from a buddy and i have been using it since. I gotta tell you, im kinda liking it. It installed in less then 20 minutes, and in less then an hour of toying around i had it setup pretty much my way. The only real change to the system itsself was disabling UAC because it annoys me.
I think i like Vista. Office 2007 still blows ass though. Open Office FTW.
