What a pity. I've got a Dell Mini 1012 with 1.6ghz and 2m ram. It's really stuttery - doesn't make a difference if I'm running at the best quality or fastest play settings. But it's real choppy. Mostly to the point where it's frustrating to play.
I've been doing most of my stuff on the netbook. I'd purchase in an instant, but I don't often want to pull out the big laptop or desktop for gaming anymore.
