At your last example, wouldn' it be better to have an event object for models and/or collections like the one for the DOM events. Then you have a start and stop method where you can simple bind/unbind this events automatically. Its inspired by the architecture of GWT where every activity has a start and an optional stop method. https://gist.github.com/1410703

at the time I wrote this, that idea hadn't crossed my mind... but I'm doing basically that, now. it works really well. I'm using a combination of both techniques, depending on the situation.

Btw, is it really necessary to delete the DOM events. Aren't they gone when the element is deleted?

i don't know if remove the elements from the DOM would clean them up directly or not. i know calling this.remove() will force jquery to clean them up and i can only imagine that jquery implemented the DOM event cleanup for a reason... but i don't know for sure

You're missing the word function in 5-appview.js (this.showView(view) {)
