3M's partnered up with Roku to provide a "big-screen" cinema experience from the comfort of your home. Announced today at a joint event, the DLP-based Streaming Projector is a 4.3 x 4.2 x 2.0 inch palm-sized device that can project images in WVGA resolution up to 120-inches across walls or any other smooth surface of your choosing with a brightness of 60 lumens. The 1lb pod-like gadget has a battery life rated at just under three hours -- a little more than the running time of most blockbuster movies -- and also features a 3.5mm headphone jack for audio out, in addition to an inbuilt speaker. Of course, you need media to pair with it and that's where Roku's included streaming stick comes in handy, delivering an array of commercial content over dual-band WiFi. It's set to ship sometime this November for $299 as an Amazon exclusive.
