My HP dv9208 laptop with 1 gig of ram is able to run Vista Ultimate with no issues what so ever. No BSoDs. No Driver problems. It doesn't run as well as something with 2gigs, but I run Aero with no issues, I play games with no problems (comparable to the specs of my system, so something like GTA SA, WC3:FT etc, I can even play Sins of a Solar Empire with little issue). Does it get choppy? Sure after either several days of net surfing or 12 hours of straight game play. Anyone who says that Vista runs like garbage on their laptop with minimum specs is doing something wrong, or their laptop vendor blows. End of story.
