Twin Phone Device (a free* idea)

Right now there is a wide range of devices in our handbags/manbags/backpacks/pockets. We have little candybar phones, little flip-lid phones, wide QWERTY phones, touch screen iPhones and so on. And a few of us have larger devices like portable media players and Kindles. My idea is based on something that is unlikely to change in the next decade: our fingers won't get smaller and our eyesight won't improve.

The idea:

I have seen the future, and the future is twin phones!

* All I ask for is acknowledgement that I thought of it. I'll never get around the realising them myself, so go for it!
