The Android back button is in the right position but does three things depending on the application:
- Go back one document (like internet)
- Go back one screen
- Leave the app
A lot of Android users just hammer the back button and then the application icon again if they want to go to the Home screen of an application.
Also it's always there even if you don't have a document to go back to. Nor it provides extra information about the previous document like the title.
Personally I would like a back button down there (next to the home button) that also holds a miniature of the previous document that animates in and out of place.
