After a cursory glance (I'd really need to look around their site more, etc, before finalizing my opinion - for instance yeah they get their tin from the conflict-free mines of the Democratic Republic of Congo, but IIRC, the DRC isn't actually all that democratic and has some serious problems - I could be mistaken though, so would need to look it up more), I think it looks really cool.

If I had the money to throw around, and they were available for the USA right now, I would gladly get one just on principle, even if it weren't going to be my main phone. But as neither of the above conditions are met, I'm going to wait and see and hope they are successful.
