Personal airline compartments. Planes would be containerized shipping units. You would go to a passenger station, pick out a compartment, settle into it. There might be 6 -8 people in a compartment. It would be driven to the airport, locked into the plane body, with electrical and corridor connections. Beverages and food would be delivered via pneumatic tubes, or you might have them preloaded into your compartment. Upon landing, the compartment would be disconnected and driven to the car rental building or parking lot of your choice.

A tape recorder with a motion detector. You put one on the sofa to say "Bad cat! Bad cat! Stop scratching." Or "No television until your homework is done."

An automated home business manager to arrange for minor house repairs and maintenance, bill paying, answering the door and dealing with people who come to door hoping to change your life.
