I keep my apple boxes, but I really dont have any reason to do so. I guess its just that they are so well designed and beautiful.
Also if you want that *Apple Smell* you can just pop open the box to satisfy you nose
Yes. Keep all Apple packaging as long as you have the devices themselves. This will not only increase their resale value, but also keep them protected during transportation. For example, if you ship a Power Mac G5 without the included styrofoam packing, the handles will bend or break off in transit.
