Yeah, that kinda rings a bell
But I've used Vista for years on a bunch of different computers and I've never "red screened" it. Maybe I don't try hard enough. I spend a lot of time in Visual Studio though, and if you don't crash things there...well, it speaks well for the OS.
I just bought a Netbook with Windows 7 (Starter) on it and thus far I'm very pleased. It's memory usage (which has been raised as a potential issue) seems *very* good to me. The little machine's only got a Gig in it, but Win7 supports ReadyBoost, so you can throw in a 2 or 4 Gig SD card or Flash Drive and have a massive high-speed cache.
