EOMA Projector
Instead of having your laptop connected to a projector, you can just pop your computer card into a slot on the projector. No more lugging around your laptop/device to play a movie, display a presentation. Now it's just the projector, speakers and your computer card in your pocket.
Unlike existing projectors that have a built-in PC, the computer doesn't get obsolete. Your not paying a considerable extra for the convenience of a built in PC.
