Welcome to the future, where if you need a new keyboard you may as well get a projector. The Light Touch pico projector throws a laser WVGA image up to 10-inches, turning any surface into a touchscreen. The projector runs on Adobe Flash Lite 3.1 and has 2GB of flash memory along with a microSD card slot with support up to 32GB.
Of course it’s also packing Wi-Fi and Bluetooth to connect to your laptop or other device. The battery life is 2 hours, which is about what you would expect. It’s very useful for a variety of situations.
