Trouble-Free Appliances
Appliance just works. TV, PDA, desktop, ...
State replicated in safe place (somewhere else)
If hardware fails, or is lost or stolen, replacement arrives next day (plug&play).
If software faults, software and state refresh from server.
If you buy a new appliance, it plugs in and refreshes from the server (as though the old one failed)
Most vendors are building towards this vision.
Browsers come close to working this way.
