You said it is "good hardware". Do you mean that the build quality is good? Is it on par with a MacBook or a ThinkPad? I have heard recently that their laptops are fairly plasticky and battery life isn't great either. Comments?
My two complaints are that the keyboard isn't the sort that I like, it's of the chiclet variety, and they only offer shortscreens (16:9 rather than 4:3). On the first complaint, this is really just my preference on keyboards. I'm a dvorak typist and so I'm a bit picky about keyboards; from my point of view, every laptop keyboard is bad, but I'm holding out hope for Thinkpads. On the second complaint it seems, unfortunately, that no manufacturer makes 4:3 laptops in 12"-15" sizes.
I have one of the ultra-thin models "Lemu1" and the body is plastic while the inner chassis is metal. It reminds me of the build on an iBook G4. It does feel a bit flimsy, but this model is about the size of a MacBook Air and so I figure some of the flimsiness is partly just physics.
