If you were on a deserted island, what is one thing you would bring along with you? I would probably bring a phone that can charge via solar power. At least then I'd have a phone I can use often.
What about you?
That's a good question. Honestly I think you answered it. Only downside with that, is how do you plan to get on the web? You can use it to probably use what you have on it already, but it'd be pointless if you're trying to reach someone without service. Cause on an island I can't see you having service.
I'll do one better, a satellite phone with solar power charging. :D
