2 phones for everyone—if industry can't get its act together
 

It's not enough for everyone on earth to have a single mobile phone—Real Networks CEO Rob Glaser thinks that everyone will eventually have at least two. Glaser spoke at this week's Mobile World Congress Conference in Barcelona, insisting that it wasn't possible for a "do everything, no compromise" device to exist and serve people's every mobile need.

Glaser explained that his belief was fueled by differences in input methods, size, and functionality between devices. No single phone can do everything easily, he said, which is why the public will be driven to carry multiple devices. "Mobile penetration won't stop at 100 percent," he told the crowd. "It will go to 200 percent because the notion of a single device that does it all isn't the way (the market is) going to go."

cellphone & GPS don't work together well, as you can't take calls & follow GPS at the same time on most devices:)

just an example

I want my phone to be able to make phone calls. nothing more.
