Just wondering if you used the System Requirements Lab software to test out your laptop. I have a Dell Inspirion 9300, Pentium M 2.0ghz, 1gb ram, geforce go 6800 256mb; and there have been a lot of applications that I have tested from that website that my system has exceeded, but run poorly after I install it. Example: The Sims 2 Deluxe and Black and White 2 (on highest settings) run poorly; while Counter Strike Source (avg. 72 fps), WoW, and Fable Lost Chapters run perfect on their highest settings with a resolution of 1280x800. Just trying to warn you if you used their software. You have to use your own judgment. Also, I wouldn't upgrade to Vista yet anyway, laptop or not. And I definitely wouldn't upgrade it on a laptop unless it was brand new.
