I think that the price paid for a $7000+ device is that they're buying the whole package, hardware, software, AND support as a whole package. So that when there's a problem there's one person that they need to contact to get it resolved (in the ideal case). I'm sure the author could go that way, buying iPads or other Android tablets (if the software gets ported), package up they software, make it auto boot, etc and form it into a complete package. The price then wouldn't be just the app, but the tablet, installation costs, and future support as well. It would be cheaper, but not by the same order of magnitude that the app is cheaper than the $7000+ device.
