When I purchased it, I was impressed by the ability to project shows without a PC attached. But in practice it seemed there were more options than I had realized.I tried out the 802.11g wireless connection to a laptop. It worked fine for slides, but was unacceptably jerky for video (MPEG2 and DVD's) although this may have been due to the older laptop I used. I did not try out the multiple laptop connection feature but presume it works the same. I also showed my presentation without a PC. This process requires you to install their software, and then to convert your PowerPoint .ppt show to the Epson-recognizable format. Place the resultant files on your USB thumb drive which plugs into the projector and off you go. Worked perfectly on simple presentations, but didn't sequence some of my fly-in labels properly. (They all three flew in at once.) So if you have a more complex presentation, I'd be prepared for surprises. It showed a folder of (non-PowerPoint) JPEG images without a hitch. Advancing them with the remote was intuitive. But "PC-Free" projection of mpeg files was hit-and-miss. One worked fine, one didn't project at all. Other features (auto-keystone correction etc.) all worked as expected. I like the product, but I'm not depending on it for video.Click Here to see more reviews about: Epson Powerlite 1715C Wireless Multimedia Projector- 3.7 lbs
