Someone giving an impromptu multimedia demonstration off of their iPod, iPhone or BlackBerry is cool the first few times you see it. But squinting at a two inch screen isn't much of a closer. Up the ante with this cool pocket projector from Optoma, connects to most mobile devices, weighs only 4 ounces with battery and can project an image size up to 60 inches on virtually any surface. For $430 it's a sleek little presentation device.
