are you looking to have this macbookair be your main machine? if so, i'd vote against it, but i'd go with this model

the air isn't made to do a heck of a lot, so why upgrade for something that's not going to get you much more. this one has a decent size hd. my current mbp has a 120gb which is getting me by just fine. the site that i listed gives points for use as cash which is a pretty good deal. helps out with other things, like apple care or something.
