The Kodak Luma 75 is literally small enough to lose track of if you accidentally cover it with a piece of paper. Basically the size of a 3-by-3-inch pad of sticky notes, it weighs just 5 ounces. But it's big enough to have an HDMI port, which means it can connect to most video sources, including mobile devices (for screen mirroring). It's also bright enough to give you a 32-inch 16:9 diagonal image for short sessions in a dark room, or an image that's roughly the size of a sheet of paper in typical office lighting. Whether you're showing a business presentation or watching a movie, that's a lot bigger than you would get on your phone, and it comes from a projector that fits easily in a pocket.
