Meet the Masterkey 4.0: a pocket projector that combines with your smartphone to turn any place into a workspace. It can project images on a screen up to 120″ for presentations. Its laser keyboard lets you type on any flat surface conveniently.
The Masterkey 4.0 has a speaker built-in, so you can use it to watch movies on a larger screen. Expected to ship in February. More info is available here.
