Apple Boxes: To Keep or Toss?

I'm in the process of moving, and I am facing a problem that is most likely unique to Mac users. Most of the time when you purchase a computer it arrives in a large, plain cardboard box with about as much personality as the generic PC that is inside of it. Apple pays a great attention to the 'out of box' experience, so the boxes are, well, very nice.

That makes me hold on to them, because they are so nice to look at, however, they are just empty boxes. So, dear readers, should I hold onto them and move them to yet another apartment, or should I break the chain and toss them away?
