Summary: This projector is so easy to carry and use, it's astonishing that they aren't making it any more . . . and there are no competitors that I can find. I never liked the hassle of connecting a PC to a projector and then hoping that my presentation would work . . . especially if I was using someone else's PC or projector. This little 2 1/2 pound gem solves that problem by eliminating the need for a PC entirely.
