i learned about single board computer on local --meetup-- group where enthusiast helping eachother to learn to program small boards ardinary etc and single board computer. i think that major manufacturer of single board computer -texas instrument. technology getting more powerful with every moth/weeks and their cost is good. i think, because price of single board computer is ok than hardware manufacturer for linuxcnc may very well incorporate single board computer with there hardware and offer finish working controller. will it make linuxcnc more robust system for final user/machine shop?
