The Galaxy Nexus, Galaxy Note, and Xoom do too. It's used to speed up GPS fixing (knowing your altitude helps resolve your location more quickly). A Google employee said that he didn't believe the barometer in the Galaxy Nexus was weather grade. There is an app called pressureNet[1] that reports your barometric data and then builds a map of the results that anyone can see. Kind of interesting but I don't know if it's actually useful for anything yet (I welcome Google Weather though).
