the E Ink shipping label will automatically update

Are you kidding me? Instead of a 25 cent shipping label they use a $100 e-ink display?

The display alone might get the device stolen.

They mentioned in the keynote they are using a kindle as the display; given that Amazon sells refurbished kindles for $65, I imagine the actual cost is a good bit lower. They also mentioned that the kindle also functions as the user-interface, so it's more than a glorified shipping label.

Tearing apart the system would yield significantly more valuable hardware than just the kindle.
