If it is size and wow factor that you are looking for then the Casio Exilim EX-S500 is a nice fit. But according to DesignTechnica the Casio Exilim EX-S500 is super small and its greatest convenience is just that, its size.

They were disappointed mostly with the EX-S500’s auto focus, grainy screen and turtle like speed to save images. The camera’s battery lasted for about 200 shots, and then had to be placed back into the included (that’s a positive) docking station for charging.
