Having used an Android phone for a while, the back button was definitely a "feature" that I'm glad isn't on iOS - it very rarely does what you expect, and has a very odd feeling to it.

Perhaps with the ICS interface guidelines being more heavily read this has improved, but on the phone I have it's a very bad interface.
