I agree with this. I put a little custom app I wrote for my wife on the App Store, mainly as a learning experience. And I decided to charge a buck to keep the riff-raff away. But that $1 makes me feel a real obligation to my users.. I've put in maybe 6 hours of work over ~5 years updating and supporting when a new OS update breaks something, all for an app that has generated about maybe a bit less than $100 of revenue. I don't exactly mind. This is the learning experience I wanted. (I have other, more successful apps on the store, but as the programmer of a small team who didn't deal with the App Store beyond getting builds uploaded.)
