I think Web App is a viable option if: 1. It's possible to write your app within the constraints of a Web App 2. You have hosting that can handle the potential load (how many million potential users?) 3. You plan on doing something that is likely to get rejected by Apple 4. You plan to give the app away for free I think allot of people overlook #2. For me one of the nicest things about writing native apps is the fact that I can focus on coding and not infrastructure, and avoid the risk of having too much (wasting money) or too little (can't service customer spikes) bandwidth, etc.
