This is unfortunately a concept idea by Mozilla, but if these guys put it into production Im sure alot of the typical "iPhone" users and up to date geeks would admirer this piece of technology. Called the Seabird it is designed to house two small projectors, either used to project out keypads weither side or used to project your phone screen on a surface and the other used as a keypad. The idea is awesome and it gets better, it is designed also to have a Bluetooth headset built into the back! For the rest of the information go here

Thought I'd share because I so want them to make this.
