Movie theaters don't have to be stationary. Take yours on the go with the 3M Streaming Projector By Roku ($300). This palm-sized box features a single HDMI input that comes occupied by the company's Streaming Stick, providing it with instant access to Netflix, Hulu Plus, Amazon Instant Video, HBO Go, and more, anywhere you can find a Wi-Fi hotspot. Of course, you're going to need a screen for watching all that content, which is where the built-in projector comes in. It uses DLP Cinema technology to provide a WVGA picture at sizes up to 120", and with help from a built-in speaker and a rechargeable battery that runs for over 2.5 hours on a single charge, you can create a theater-like experience damn near anywhere.
