It seems i'm one of the very few with a good experience with Vista.
Runs equal to or faster than my XP ever did, not experienced any bugs or anything, i'm actually really happy with it (Also loving running Crysis in DX10, drool).
Also, while using desktop app's, i've never seen my RAM usage go above 900mb (~400mb after boot has finished) out of the 2gb i have. So what if XP wouldn't have used that much, i still have 1.1gb headroom left.
I'm not trying to say that you Vista haters are incorrect in your opinions, it's just a shame everyone hasn't had the same experience with it that i have had.
