Getting a computer with Vista on it was the reason I got serious about trying out Linux (had run a couple of livecds prior, but my old computer was ooold, with not much hd space or RAM, and having never installed an OS/partitioned before, I was too chicken to try it) - it would crash for realz every 1-2 days, and it took me forever to figure out and download the fix. And even with 2GB RAM, Vista was slow, gahhh. Yeah, don't miss it.

From Googling it, it looks like there is trouble with the ATI Radeon Mobility HD 3650 - you can dl a driver from ATI, but again, people don't seem to have had luck with it. Ubuntu documention and installation guide, if you haven't already checked it.
