From the Compare page http://www.apple.com/ipad/compare/ http://www.apple.com/ipad/compare/, it looks like the "iPad Air 2" is the first iPad to carry a barometer as an additional sensor. I missed the keynote, did they discuss this? Doesn't seem as usable as a step-counter since it's in a tablet, how does Apple intend to use the barometer for this tablet? Also, is there a single Technical Specifications page for the iPad Air 2? I can't find a list of sensors in the device, outside of the linked Compare page. Edit: Here's the full specs page: http://www.apple.com/ipad-air-2/specs/ http://www.apple.com/ipad-air-2/specs/
