Isn't it just in I/O device for our main connections?

iPhone may be changing the way US users deal with mobiles. Why can't we just get data with it, as we so elsewhere?

clipped from www.news.com In data provided to The New York Times, Google disclosed that it received more traffic from iPhones this Christmas than from any other mobile device, despite owning only 2 percent of the smartphone market and less than 1 percent of the overall mobile-phone market. That means that while fewer people own iPhones, those who do possess the device use it to access the Internet much more than those with competing handsets.

See what I mean? Here is a story about scientists working on enabling one to use a phonecam as a "3-D mouse."

"I like this because connecting phones and computers is just such a pain right now," says Mark Dunlop, who works on user interaction and mobile phones at the University of Strathclyde, Scotland. "You should be able to see something on screen and just get hold of it."

Mobile phones may be ubiquitous, but people are only now starting to use them for more than just calls and messages. "We're still looking for more natural ways of using them to interact with other devices," Dunlop says.
