1. The processor. Intel is late on their delivery of their ultra-low power 45nm laptop chips. Clearly, the MacBook Air is the exact computer that these types of chips belong in. So Apple and Intel spun it as going out of their way to do something special. That something special was jimmy-ing a 65nm chip onto a board that was made for a 45nm one. The 45 nm chips will be arriving by mid-year and will likely be put in rev 2 of the MacBook Air. They will use less power per CPU cycle and that five hour battery life could easily turn into six - and with the reduced power consumption, they might be able to crank the processor speed up to and beyond 2 Ghz or maybe even fit in some more wireless options.
