It's true if you're comparing apples to apples. If you have two devices which are otherwise identical, then the one with the EInk screen will last longer than the one with the LCD screen. That's what the selling point is talking about.
Usually though when comparing random device A with random device B, there is a lot more going on that effects the battery life than just the screen.
