Dell made a laptop with similar specs called the 'Adamo' for a while. It's small, light and sexy, costs about half as much as an MBA, and Ubuntu worked out of the box.

A good alternative if you'd like to avoid the Apple flavored kool-aid.

Lenovo's about to release the ThinkPad X1, with relatively beefy specs and the MBA's form factor. Do want. It's freakishly expensive though (almost $3K).

I couldn't find the "Adamo" listed on Dell's US website, but it is listed on Amazon[1] for ~$1261. That's only a touch less than a MacBook Air. Where did you find it for "half as much?"

I bought mine last fall for $900, and I guess I'm not up on the latest MacBook pricing. Sincerest apologies.
