Me neither. It's very frustrating when people come up to me and say "aww that sucks, it doesn't have an optical drive". I can't remember the last time I used my power book's optical drive
MBA is definitely not designed for use as your sole computer. But maybe with external optical drive (which I have NEVER used, complete waste of $100) and apple 1TB external hard drive. Possibly could work with that.
I live in NYC and I carry it everywhere I go. I think nothing of flipping it open to jot down a few lines, to check something, to reply to email... in the park, on the subway, in line at the drugstore even.
Until you've experienced how light it is day to day, you can't really understand what a great experience it is.
I love so much about my Air, I guess the best is the sheer portability - I can hold it with one hand comfortably while walking around the house (watching webcasts/movies etc)
(and the lack of dust/crap attracting ports all over is a plus too)
