Here’s an interesting usability metric – of over two thousand installs of the Owner application on Android/G1 – there’s a (very) small percentage of users that either do not understand they have to click “save” to store the information they type into the form, or are overlooking the save button, or expect the information to be saved when they hit the back button (without clicking save).

I’ll have to push out an update to warn the user if they try to navigate off a form after changing some information but not saving.
