I also think that with SP1 Vista is better. Mine has been up since mid July with no problems. Of course I had to hunt around for drivers but once installed it's running well. I installed W7 a couple of days ago, made a 30Gb partition. It doesn't look bad, keeping in mind that it is a Beta. I have 2 major issues though, V card Sapphire 9550 is not running, (tried Kyle's rec also) and at TV tuner, live TV is jerky. I mostly use it for work, don't have any big games running. To be honest my machine isn't even in that caliber. Let's not forget that XP didn't start off with just the snap of a finger.
