Kind of intriguing if you ask me. Not as a GPS unit, but to be able to text friends where there is no cell signal. I hunt a ranch that is on/off getting cell signal, so it really burns up your battery fast and you can't always communicate by text. If you can text up to 5-10 miles without using cell towers that is a plus in my book. And the battery they provide lasts up to 4 days.
That said, not sure it is worth $75 per phone to do it. Once the technology is out, price should come down.
