I really wish they'd get rid of the hardware back button. Some apps, like the gmail app, use it to mean "go back up one level in the UI" - for example from reading a mail back up to the list of mail in your inbox. Other apps, like the browser and maps, use it to mean go back through your history (just like the back button in a desktop web browser). It causes just enough cognitive dissonance that I frequently end up trying to use it for the wrong thing. It's very annoying.
