hmm... i just downgraded from Vista x64 to XP x86 SP3. what i got was MUCH FASTER SPEEDS but abt 1 day into using it, i got a common problem i seem to always have sooner or later, when i start XP, sometimes it lags (maybe cos i clicked something too fast or what). when i go to task manager, i see that under the Username column, its blank! so it seems like explorer got corrupt or something... looks like its true that XP is faster but less stable. i always liked XP for its speed and Vista for its looks. but i nv thought Vista was actually more stable... thinking of getting a Mac, but i just saw Apple's site and it seems "Snow Leopard" will be out soon? so i think i will go back to Vista for now? http://www.apple.com/macosx/snowleopard/
