Touchjet Touch Screen Projector
It fits in the palm of your hand. Yet its screen is larger than anything you can fit in your backpack. The Touchjet Touch Screen Projector combines the innards of a tablet with a projector and an optical sensor, allowing the projected image to work as a giant 80" touch screen. It has 4GB of flash storage and another 16GB on an internal SD card, a 1.6Ghz dual-core processor, built-in Wi-Fi and Bluetooth, and offers compatibility with apps from the Google Play store. Arrives with a remote, as well as two styluses for interacting directly with the screen.
