2 Gigs of Mem sorta put a dent in it...
I have been running 64bit vista beta and RC 1 on a decent comp - 2gig 3500+ XP and cannot stand it compared to windows xp... The place I worked at allowed me to build a computer with a dual Core Amd processor and 1 gig of ram...the results were even worse. Granted this is pre-release garbage ware but Vista seems like its just an excuse to force upgrades on older machines with no real return or value in the process.
My other thoughts are that the O/S seems strangely like a Mac X machine with dirty underware (sorta a pun)... it looks pretty on the outside but when you get into its pants it starts to stink in a real hurry.
In my dream world microsoft would figure out a way to make use of that free OS called linux and begin to function more like a computer management system and less like a theif in the night which steals your resources and sales them to the highest bidder...
I doubt that when I do make the change to vista I will enjoy it.
