I know it says $379, but I helped my buddy set one up that he got on boxing day for $299. I like it way better than my Acer Aspire One.
The processor is the L110 which isn't even listed on AMD's website yet, but from what i've read it's a development of the Athlon 64... but runs on far less power, probably due to a newer manufacturing process.
The TDP for the L110, its chipset and ATI X1250 total 21W... Not too shabby for a chip that's a development of a desktop processor.
It's only a 1.2Ghz part, but i read some benchmarks somewhere yesterday and it beat the Atom in most of their tests. And it definitely feels faster than my Atom
