Technology has a tendency not to hang around popularity for too long a time, excepting things like paper of course. Before smart phones, there were cell phones, and it is more than likely people did not think they would need anything beyond their mobile phones, maybe a niche market for something like Blackberry's. But now smart phones have completely overtaken the market, and it's almost impossible to live without one. How long do you think it will be before the next big invention comes and sweeps away these pocket computers we have? Do you have any speculation on what this new technology might be?
