Readability and ultra low energy consumption (plus: they are awesome and produce a soft sound like a distant waterfall).

Also, contrary on what I have seen on LED matrices or other RGB/pixel based displays: they won’t display advertisement which otherwise manages to sneak in – too close to information.

I wonder how their energy consumption actually compares. Electric motors moving relatively heavy physical cards is far from free. I wouldn't be surprised at all to find that an eink display beats the pants of of a split flap display in terms of energy consumption, but I don't have the necessary equipment to test it.
