If you've ever had a cell phone, you know how frustrating it can be when your network fails. Areas with little to no signal can be absolutely infuriating, and overcrowded events can be just as bad.

It's an incredible concept, but with an asking price higher than most smartphones, there's no way that this implementation is going to take off anytime soon.
