I've been thinking that lately. Those look like really cool little devices. I think I might wait, though, and either get it at a lower price or see what they do with the next revision. The battery life is a little low for me at 2.8 hours. Other than that I think it's really cool.
I got an OLPC XO just to see what kind of a job they did with it (good, IMO) but I am going to get an EeePC, I think.
Had lunch today with a friend who is a long-time Apple afficionado and the Air launch has him thinking that Apple has Jumped the Steve -- was amazed that this was all they had to show. "Only one USB port?" he said, "and still it's 3 pounds?"
You could view this as a problem of raised expectations. Or not.
