Unless something is invented that is better than the Glass model, Glass will fill our lives. Maybe not so much at home but in the work place. The benefits of "information at a glance" for couriers, doctors, technicians and so on, are many.
It will also take a good portion of the mobile phones away. If you use a mobile/cell phone whilst on the move, why would you use a phone when you can communicate better with Glass.
Businesses and geeks will pick up Google Glass like "ducks to water".
