Acer 8204, though it's just a stretch above your stated limit. I'm very happy with mine, which I've had since late Feb. Do check other threads on it so that you know what others are unhappy about with it.
I've had my hands on one that I bought for my daughter for her graduation - very nice. And you'll probably like OSX, even if you mainly use XP. If this option had been available a month ago, I'd have bought one.
Anyone know what this program is? ProcessExplorer indicates that it's associated with eRecovery. The thing is running in the background eating 50% of my CPU. Thoughts on how to get rid of it if inessential?
