Augmented reality is starting to get such an old dry idea now that it's ready to explode. The combination of compass and GPS is finally going to make it possible. The first phone that had this combination was the G1. So they get the cred for a lot of the innovation happening in this space. The new iPhone is also going to have a compass, and others will follow.

This shows the power of adding more sensors to a phone and hoping for the best. If you have an open platform you can get really lucky. Good work Google.
