I really like it when my gadgets can do more than one thing and when my gadgets have hardware that can do more than one thing I get excited. AuthenTec is talking about its contribution to the LG eXpo smartphone.

The eXpo uses the AuthenTec smart sensor that not only reads fingerprints for security, but allows navigation too. The sensor is sort of like a track pad fingerprint reader combo.

Check out the LG eXpo, a slider with a pico projector inside. This full QWERTY slider is also packing a 1GHz CPU, a 3.2-inch touchscreen, 5 megapixel camera, a microSD slot, and the removable Texas Instruments projector.

The eXpo is running Windows Mobile 6.5, and it will be available from AT&T on December 7th for $199. That’s after a mail in rebate with a two year contract. Then there’s an additional $179 if you choose to get in on the projector action.
