May sound dumb, but I'm working on an idea for a cheap laptop mount. At second-hand stores I always see those brackets for mounting TVs on walls like you see in motels, hospital rooms, etc. They're very similar to the commercially made laptop mounts and I think they could be converted to that use pretty easily. I picked one up for $5 the other day and converted it to mount on my Yakima cross-bar while in camp. The S-shaped tubing comes down and supports the platform at about waist height. I mounted my Coleman stove on it and it's awesome. Don't need to take up table space and it's out of the way of the kids. Just a thought.
