I'm in the midst of using Ionic to build a simple app that consumes a JSON API and am finding it very good to work with. It seems pretty solid for a beta product. I'm new to Angular but it seems like you can get a lot done without knowing all that much about it's inner workings, which is great.

I would suggest sitting down and seeing what you accomplish using it for a few hours. I did this to compare Ionic and jQuery Mobile. The app is far from complete, but I'm liking it so far.
