Fujitsu have revealed a new phone called the Fujistu F-04B that has a dual keyboard setup, projector and a 3.4" screen that separates from the keyboards.
When separated the keyboards and screen connect over a Bluetooth connection. Each part of the phone contains a battery to keep it running. The screen section of the phone works independently allowing you to detach the keyboard to slim the whole unit down a little and then use the keyboard when needed. Alternatively you can attach them together and access the keyboard like a slider phone.
Another feature that is available on the phone, although it's optional, is a 6 lumen projector allowing you to create a larger screen with an 854 x 480 resolution of I'd estimate here about 50 - 80 inches in the right lighting conditions. The projecotr has an 800mAh battery that is good for projecting 2 hours of video at the highest brightness setting. When connecting the projector up to the phone you actually have to remove the keyboard which then acts as a remote control for the projection unit.
It's an interesting idea for a phone and I quite like the detachable keyboard feature. At this moment I am unsure if it will leave Japan though.
