I think I have finally found the Netbook I was looking for
I've been looking for an affordable 11" (or hi-def 10") netbook for some time, but came across this machine this evening. It has a 64bit Athlon chip, 2GB ram, 250GB drive and a 1366x768 screen. It also has dedicated graphics, and plays HD video (720p MKV) without a problem.
So far I'm quite impressed - sure, it may be Gateway, but they are currently the only ones with the machine I want.
