Loving the potential, and I have invested in a battery pack suitable for 3 days of typical use as well as a solar charger. However as mentioned in the article it has a long way to go and just isn't ready to replace a standalone GPS or map and compass. I'm the type who believes it will never be though, with my luck even if the technology matures I'd end up dropping my phone and breaking it lol

I still think it would be amazingly useful to be able to store and cache an area on google earth on your phone for offline use (say 10 mi x 10 mi max zoom and another few miles moderate zoom) that would work with GPS (either manual entry or through phone gps) to find your location on the map. Then you can literally have a birds eye view of the area you're in. If weather is bad, what's down that trail to the left? The right? Oh an abandoned cabin! lol
