I’m also considering the same thing…even taking it one step further and building my app based on jquery mobile. I like the navigation and total ajax interface. They’ve done well to handle the navigational browser history and given a solid base for extending it.
Hopefully this post will get to the top, maybe someone else has some experiences with it?
Now I am a complete noob when it comes to Yii and web-dev (just starting), but doesn’t the jQuery Mobile take a heavy front-end (complete client-side rendering) with a RESTful backend, approach mostly ?
So far in my attempts at learning Yii, I seem to be getting an impression (hopefully very wrong) that Yii integrates "just enough" jQuery, but it might not be natural to to write a RESTful app in Yii.
