There are Apple collectors who are interested in just the shipping boxes. I've put up for bid an empty retail box for the Apple iPod 10GB 1st generation model.In my research, Apple had two different boxes for the 10GB model, and two different boxes for the 5GB model. The 10GB model had either Jimi Hendrix or Miles Davis, while the 5GB box had either Bob Marley or Billie Holiday. So in a way, a die-hard Apple collector would need all four boxes. The box I've up for bid is Hendrix.
It'll be interesting to see what bids or offers I get for this.
