I was interested in hearing how things are in developing apps for iOS vs Android; specifically, some things are

1) Is it obvious to be iOS-first? This goes both for when releasing the first app for a product or service, and then updates and/or platform priority. (I understand this could depend on the particular service/product and market, but I would like to hear!)

2) How do the development tools compare for typical apps? What about for games or CPU/GPU-heavy apps?

3) How painful is it to deal with the number of devices with Android vs. the relatively few for iOS?

4) What are the current issues with the app review process?
