I think there's probably a market for a personal cloud, which probably sounds dumber than personal computer did in the 80s. What I mean by that is a computer somewhere in the garage, like a furnace, with enough compute and storage to drive all the devices and appliances in a house. In this model, devices do not have CPUs or memory, only input/output and a network chip.

The way this would work is for the computer in the garage to have the ability to divide itself arbitrarily into VMs for each purpose, with an ecosystem of images designed for things like fridges and gaming consoles. It should be possible to add or upgrade compute to the device in a hot swapped fashion, and because it doesn't have to be in a thin tablet, it could be easily cooled.
