Your use case is particularly apt for frequent fliers. I've almost had a tray table-supported laptop destroyed on more than one occasion by a reclining passenger in front of me. It would be amazing to just set up a small keyboard+trackpad on my lap and not have to even pull the computer out of its bag.
If I could do this, I wouldn't even care how ridiculous I looked.
