Kite

Make your own device

"Kiteboard is a compact, ready-to-use compute and connectivity module which enables OEMs/entrepreneurs and makers to build custom connected devices/appliances for vertical specific applications."

Making my own mobile device sounds like a fun, but I can't image to use it. I think it is for some tech fans only. At this time i couln't find price of this product, but I don't think so it is going to be cheaper than some low end smart phones.
