If you've been searching for a non-DIY Bitcoin mining machine, there's now a device that could meet all your needs. Announced earlier today, the 21 Bitcoin Computer is a pocketable, Raspberry Pi-powered tool with native hardware and software support for the open-source, peer-to-peer money protocol. 21.co, the startup behind the new product, says you can use it to seamlessly buy or sell digital goods and services from a custom command line interface. What's more, thanks to a built-in payments system, you can also set up the Bitcoin Computer to sell your own API calls (like language-to-language translations) and even create a personal store for virtual items.
