For 30%, you get: order processing, distribution, update management, and some marketing for your application. The order processing alone is is worth it in the case of a .99 app - the CC fees alone would usually be more than 30% in that case, plus you never have to deal with chargebacks. Of all the problems with the app store, I think the cut that Apple takes is pretty far down on the list - in fact, I find it downright reasonable.
