> Is there any practical use for color ePaper yet though? Years ago, the cafeterias at Microsoft switched from using regular signage for their menus to giant plasma TVs that showed a static image of the menu that had been there. The menu at some of the stations (but not all) did change daily, so there was some, slim, benefit, perhaps. After awhile, they moved over to having a slide show on the screens that alternated between glamour shots of the food, and the menu. Now you could only see the actual menu for a fraction of the time, and despite being a speed reader, I'd often have to wait for the menu to come back around multiple times before I could read it all and decide what I wanted to eat that day. But it sure did look modern! Further irony, IIRC that was around the same time I volunteered to be part of a campus wide partnership with the local power company and I stood at a desk in the cafeteria handing out free CFLs bulbs. The tl;dr is that companies will invest in expensive, less useful, signage, if it is perceived as being cooler. Heck it isn't like menus carved/painted on wood have particularly good contrast ratios, but they still pop up now and then.
