At some point I wouldn’t mind getting a touchscreen, something small like a Raspberry Pi, enclosing everything and mounting it next to the Nomad. It would be great to have an ‘all in one’ system at the machine for drip feeding it.
ChromeOS would be an option for OS support as well, but I’m not sure it would offer everything you need for communication. I’m setting up a ChromeBit as I type this for an automation project at my day job. They’re very interesting devices and you can’t beat $84.
