"However, I can't help but feel that this paradigm would work best when your app is a fairly basic CRUD thing" Honestly, this is something I've been struggling with coming to terms to for a while. Really, what mobile app isn't just a CRUD thing? Literally every 3rd party app I can think of on my phone talks to some REST service in some way. Even the video games, photo editors, notes apps, etc. They all use the cloud where the cloud contains most of the business logic and the app is a thin visual client proxying the data. You could argue that, for example, a first person shooter is not CRUD heavy. But after the match, when you're looking at leaderboards or sending friend requests or chatting with your friends in the lobby...guess where that UI is updating from? Yep, another CRUD API. It's everywhere. I really want someone to prove me wrong because I want to expand my horizons - what the hell isn't a CRUD thing these days, other than completely offline apps?
