Nobody ever said that no device with an eInk screen is ever going to have a short battery life; merely that eInk screens use less power than LCD screens. That statement remains true.
Yes and no. That fact about the screens is true, Harry, but it is usually bandied about as a selling point for devices with Eink screens. It is usually said that you choose a device with an Eink screen so you will have a longer battery life. This is when it becomes not true. It has become marketing hype.

I think the difference in our views is because you are talking about Eink screens, and I am talking about _devices_ with Eink screens. We're not quite talking about the same thing.

BTW, I have two devices with a similar sized battery to the DR1000S and longer battery life. One is the NEC MobilePro 880. It's a laptop with a 9.4" touchscreen. I'm getting about 8 hours battery life from a 1.4Ah battery. And my PenCentra 130 with an 8" touchscreen used to get about 5 hours from a 1.3Ah battery.
