I remember a few years ago when there was a ton of buzz about micropayments being the future of ecommerce, followed by a backlash on how micropayments were a horrible idea, and would never overcome the transactional costs. In the meantime, iTunes and S3 (among others) have quietly been building great businesses on top of micropayments — I think one important difference is that originally people thought of micropayments as paying small amounts to many different people, vs. paying incrementally to the same person/business.
