With a real barometer it could be an emergency backup heads up display in a small plane (altitude, heading, etc). Most of the barometers in android phones are far too insensitive to do that though. The cheap pressure sensors in the android world only cost a few bucks so why not toss it in there, maybe someone will figure out something to do with it. Too bad apple won't add something truly useful, like the swype keyboard god forbid they might actually have to pay swype to use it so that just can't happen.
