In some "oh look at that horrible, horrible car wreck!" kind of fashion, the fact that Android so utterly screwed over the entire concept of the back button from the Web is sort of fascinating to me. Except for how it drives me nuts daily.

The problem is that the back button is involved with task stacks as well as being used by apps themselves for their internal UI. So when I am using a, you know, web browser on an Android device, the hardware/OS back button will only sometimes act like a real browser back button: other times it will dismiss the browser app entirely.

Sure on the one hand I completely get the logic of it all. But the final effect is really only to drive me nuts. Best way to drive somebody crazy? With random negative stimulus.
