I have a thin client with a 366MHz AMD Geode. YouTube anything (even @ 240p) almost literally sets it on fire, even with an extremely lightweight Linux distro on it. It doesn't so much skip frames as it does entire 10+sec chunks... and that's with 512MB RAM. I can put a gig in there, sort of... system has a low-level timing issue, I found out from an insider guy -- there is ONE make and model of 1gb PC2700 out there that will work. It's an APacer brand stick and it's absolutely hen's teeth because I've never found it. I've been looking for multiple years now...
