content: Physical computing, it's essentially an extremely small link's computer that has I/O headers. You can run them like a small server that hosts a webpage on your local network to control something, or use it as a tiny backup server, or put it in a box and use it like an arduino that runs python, ruby, JS, or whatever you want to use. Use it as a DIY smart TV, prototyping, etc. Or just use it as a portable computer that is MUCH cheaper than a laptop. Got a TV to borrow, get a bluetooth keyboard or something like that.
