When I was in college in the early 90s I was watching an episode of Star Trek: TNG and there was a prop that was supposed to be a small alien bug containment device or something) that looked like a grey, hard-plastic ribbed binder. He flipped the top open almost like a modern laptop. It looked like a futuristic Trapper Keeper. I kept looking at it thinking "that looks familiar". That's because it WAS a futuristic binder that I had in the next room. I went to get it to impress my roommates, but the episode went off. Years later, I've tried to either track down the binder or find a screen grab from the episode, but have failed in both accounts.
*EDIT* HA!!! Flickr saves the day!!! Here it is, a Nintendo Power Binder:
