How about both?
I have both, and I use them equally as much as each other but for different tasks and wouldn't want to be without either, in fact if you asked me which i'd have to get rid of first it'd be a difficult decision.
How about, go with the iMac for now. You say the MBA option would cost you about $400 more, I make the assumption you have the extra cash there. Save up for a few more months or whatever until you can afford the base model MBA and bingo, you have the best of both worlds?
