If your wallet is bulging with dozens of pictures of your pets (or kids, whatever you want to call 'em), leaving an impression in your back pocket and an unnatural curve in your spine, you should probably consider Matsunichi's Photoblitz PV110 digital photo keychain. Capable of storing 56 images for display on its 1.1" OLED screen, the unit connects and charges through USB2. Our best idea? Store a picture of your car to help would-be thieves steal your wheels.
