The Continental ones with the two separate zippered compartments are especially handy for keeping cords and such organized - I keep one with my empower charger and travel adaptors, and a separate one with spare laptop battery, network cables, etc. Sometimes a 3rd one as a toilet kit.
The NW/KLM ones are great for keeping pens, pencils, markers, crayons in - schoolteacher friends seem to like them. And I guess folks travelling with kids could use them too.
Gave a few to friends and family that normally ride in the back of the bus (do they even give eyeshades in Y?)
But . . . like you, I have a drawer full of them left that I'm not sure what to do with.
