...and this is why developers should never be in charge of usability/design.

simplification enhances usability. the vast majority of smartphone and tablet users are happy that all that complicated IT/nerd stuff went away on their devices.

the complications you would introduce by user switching are big. you need to add UI elements to tell the user at all times in which mode they are, you need new dialogs to switch, etc etc. the android status bar already looks like a badly maintained win xp install with all that crap in it.

built by developers for developers. brrr.
