I have an XP laptop and mine runs great. I have some of my crew that does use Vista and had not experienced any issue but the best bet I think is to wait for Vista to issue service Pack 2. If you remember XP also was very buggy when the 1st release came out. It did not become more stable until Service Pack 2. So hopefully Microsoft will get it right on the Service Pack 2 relaese this time. I have tried SSL on vista and it is not smooth at all, al ot of USB drop outs and freezing.
