XP SP2 rock solid OS, I have used vista as my main OS for one whole week... yes one whole week and I put XP back on today. Vista is a pile of crap they should not of released it. Its very buggy, with windows explorer crashing every time you try moving a file over 1GB. And then firefox and IE crashing. Its terrible, the only thing good about it is the nice theme. But I would rather have xp theme and a solid stable OS, than that thing they call vista which is meant to be a OS. XP does not really need a new Service pack, I have slipstreamed all my updates up to march so I only had 12 updates to install today.
