How is SPUD better/different than every other portable projector?

Every other portable project requires perfect lighting and a perfect wall, meaning you cannot use it anywhere, like SPUD. Additionally, they typically have lower brightness, lower resolution (often projector companies mislead that they have high resolution, that is actually upscaling; usually the native resolution is 858 x 480 or lower), and require a much larger projection distance than SPUD. Typical portable projectors usually have relatively short battery life as well. We think you should be able to have a larger screen experience wherever you want whenever you want to have it -- and that's what SPUD gives you!
