Centralise the complexity:
Every other essential network in the world works the same
way. A simple appliance accessing a powerful
professionally managed network of economies of scale.
Except for the PC; with electric power generation,
television, telephony, we centralise complexity and have
it managed by professionals. Give the end user a simple
appliance – a cellphone, a television, a water faucet.
Your PC need only be an Internet access appliance.
