Qi Hardware is now shipping its first "copyleft hardware" device, the ultra-portable Ben NanoNote. The palm-sized notebook is designed to be a hackable hardware platform for Linux developers, akin to what the Arduino board is for electronics projects. Key to making that vision a reality is keeping every part of the product open: the circuit board designs are licensed for reuse, every chip included uses open-source drivers -- and the system, of course, runs embedded Linux.
