I'm getting into replacing VMs with microcomputers, starting with Raspberry Pi 2. Compartmentalization using hardware is clearly better than with VMs. See https://github.com/maqp/tfc/ and https://cs.helsinki.fi/u/oottela/tfc.pdf
That is pretty interesting. I can see a day, where business travel could be transformed. Hotel rooms, conference centers, restaurants.... have monitors, and you bring your stick computer. Even within a household, more monitors, and fewer boxes. I'd still want to lug around a keyboard.... as I don't like communal keyboards. Many people are disgusting. But there are already nice, ergonomic, light, folding wireless keyboards. I can really see the school application. Instead of issuing laptops, issue computer sticks. I think there could be something to this.. -Frank
