Nice, thorough write-up. For people considering Backbone, though, I will say that I've written several non-trivial Backbone apps, and negotiating the form view re-rendering problem is not that difficult and certainly does not require an extra data binding library. Also I've had no problem integrating the Chose plugin into Backbone apps. Dealing with deeply nested views can still be a bit of a headache, but I prefer the extra control over view rendering that I get with Backbone vs. soem other frameworks (I have no experience with Angular).
