"Amy's (local) personal cookbook app" sounds great in theory, and that people will do this for the novelty, but my point is that this will not be a long-term trend. Largely because people will want more features in their apps beyond the prototype, they will find it hard and decide they'd rather be doing the cooking than cajoling, and go back to using the same app their peers do so they can be social and share, or even just send the recipe from their phone to the tablet on the kitchen counter
Humans are largely emotional creatures. "I made this" is enough of a driving force on the small scale, and I want the button here, and not there. No app developers since winamp have offered that level of customization at their level. There will always be people who refuse to use technology, and others that dive in deeply, but most are in the middle. So if it's 20 mins a week after an initial push to add a feature and send it to TestFlight or Dropbox an .APK then I see that being way more common that you believe.
