No help here.
I believe and enforce no electronic toys whilst camping.
My DIL always sends various electronic toys for my DGD.
I always conveniently forget to pack 'em.
Wonder when she'll get the hint?
I have the Pico projector, and I don't really recommend it. It's tiny and works with standard iPod connections, so super compact. The picture's not all that great, even in a dark room using a projector screen. But for $175, it serves it's purpose for the kiddos.
We also have a Epson Movie Mate. It will play DVDs or the video camera or even streamed movies from iPod. The image is bright and the integral stereo speakers playback well. We usually have time to get in a movie before the skeeters get too thick and/or curfew hits.
