"I'd like it if the Air was about half the size. I don't know why Apple won't make something in between the Air and an iPhone." --pg, http://paul.graham.usesthis.com/

On another note, the 2 GB of RAM on the Air worries me--that's not a large amount anymore, and I'm dubious on swapping a lot to the flash memory--it'll be faster than swapping to HD, but swapping--especially if it happens a lot, as it would with only 2 GB of RAM--is a use case that puts a lot of wear on flash memory.
