The projector itself isn't very big, which keeps it in line with most technology these days. It is small enough to fit in the palm of your hand and only weighs about one pound, making it easily transportable. In addition to that, the projector is capable of projecting an image of up to 120" diagonally with a resolution of 800 x 480, which isn't the best that can be offered, especially if you are serious about HD content, though it is respectable considering the size of the projector as a whole.
Adding to the convenience of the device, this projector is also battery powered and should last around 2 hours and 45 minutes per charge, meaning it should last you long enough to watch an entire movie. But if you are watching a movie near an AC power outlet then losing power won't even be an issue. Just make sure you bring the adapter cable along if you are planning on having a movie marathon.
Integration comes through HDMI, meaning you can gain access to all of Roku's content, including Netflix, Hulu Plus, Amazon and Crakle. You can also connect this projector to an Xbox 360, PS3 or any other HDMI-compatible device. Roku also gives you access to over 600 channels, so you will never be at a loss for content.
Internet connection can be accessed via WiFi while a small remote is also included, allowing you to control your projector comfortably from wherever you are sitting. The projector also comes with small, built-in speakers as well as audio out for hooking up additional sound systems. You can pre-order the projector right now at Amazon for $299 with the projector actually shipping on October 22, 2012.
