Having worked in a reseller for the past year and a half... especially having sold a fair number of the Airs, I can safely agree that for most people, most of the time, there isn't much a need for the optical drive.
You cannot be serious, are you? I mean check the top 5 sellers in the apple store, the air isn't even on the top 5. Base on your logic, just because a lot of people buy the white macbook with the optical drive, I can safely agree that for most people, most of the time, there is a need for the optical drive
