If you're looking for an idea, I use mine with libsane/ImageMagick to drive a USB scanner workflow. Press the button on the CHIP, scanimage executes, then some `convert` bits with ImageMagick, and it winds up on my NAS.
Ditto that! I use mine as a Linux workstation for the desktop .. like, I literally leave it on my desktop with a pencil through it, and treat it like a little workstation.
Great device, amazing price, and finally: the year of Linux on the desktop! :P
