The big change always gets down to cost. It always gets down to moving the technology down to the level where more people can afford it. If you look at the radical change in computers, it was the change in cost and performance. That's what made it so people wanted to have computers. Utility went up relative to the cost.
Price is established with cell phones.
There's kind of a threshold as to what people are willing to pay, so what happens is you keep adding capabilities that will add value. So while there are people talking about disposable cell phones to the extent that the technology lets the simplest devices become less expensive, it's more a matter of increasing utility and capability with the cost. That's the big change and it's not just cell phones. I happen to be a big believer that the fixed Internet will continue to be a very powerful driving force even though everything is going wireless. There are tremendous advantages to a piece of fiber-optic cable.
