Vaio X has a standard DC barrel pot, ive powered it on anything from junk-heap printer wall-warts to 20-cent car-adaptors to lab bench-supplies without hassles.

other things it has over the air are half the weight owing to carbon fiber vs aluminum and a smaller battery owing to an Atom CPU (a feature - can tell which code is slow), and a full array of hardware ports and slots, a matte-screen with almost 0 reflected light readable in direct sun, a fan that is off most of the time, and GPS/3G. gma500 is main problem, but Alan Cox's driver is getting OK enough to use

The Vaio X has been discontinued. The nearest equivalent to the MBA 13" I'm contemplating is the Vaio Z, at a cost of nearly $1000 more.

Apple products have always been derided as "under-speced and over-priced", yet customers keep voting with their wallets to the contrary. Knowing first-hand how those Vaios tend to blow their superior specs in the oddest ways, I'll take the Air.
