I hate using my laptop on planes. The traytable is never quite big enough for my computer, and I have to lean forward and hunch over to see the keyboard.

Many people must have the same problem, because Keynamics is bringing ergonomics to airplanes. The company is introducing the Aviator laptop stand, which sits on a traytable and props up a notebook to a comfortable typing angle. The stand lets you sit all the way back in your seat, relax your wrists, and open up the screen to a good angle. It's designed to stay sturdy even during turbulence or when the big guy next to you bumps you on the way to the bathroom.

This product is aimed at the business traveler and so, of course, it's portable: The stand breaks down into three pieces and slides easily into the side pocket of your laptop case. It won't load you down, either, because it weighs just 9 ounces.

I don't do much flying, but for $19.99, I wouldn't mind taking one of these on my next Amtrak trip.
