I recall seeing support for Arch Linux listed for this device in a description I read at one point... so I'm pretty sure it's still an option (most likely, it's a Arch Linux ARM install dirivative if something is already out there)... Looking forward to getting my hands on one of these myself so I can see exactly what it's capable of (and toss Arch Linux ARM install on there asap!) because it is DEFINITELY one that has my attention!
If "custom" was mass produced, it would just be a "product line..."
Help grow the dev population, have your techs trained and certified!
