I think this is one of the cooler gadgets Ive seen recently, Ill be getting one. There have been so many times I have wanted to do a slideshow at the end of a shoot (think weddings) and Ive never been big on buying a super expensive projector and then lugging it around with me. The 3m Micro Projector is the size of a cell phone, it can project images up to 50" and costs about $350. It works with all video out devices, computers, cell phones, PDA's etc.
