I'm set to begin college in fall, and I've heard there are many debit/credit cards with favorable terms for students (for example, "Blue" from AmEx) Can one earn miles on the special student cards, or does this only work with the "regular" (and presumably more expensive) cards? I currently belong to the DL, AA and NWA frequent-flier programs, though I have also been considering United College Plus. Naturally, I would prefer the lowest possible annual fee. I'll be attending college in Philadelphia, Pa, in case this makes any difference.

I'd be very grateful for any recommendations!
