Except that it's the technology and power management that defines the battery life. Cost, functionality, size/weight have nothing to do with battery life.

And what I'm hearing people say is that there are tablets, possibly for comparable price, but in any case similar size and weight, that do more for longer on a single charge than the DR1000.

Likely because the tablet is using power management, which doesn't exist on the DR1000 yet. As I said, there is a lot more going on with the battery life story than just the screen. However, saying that eInk uses a lot less power than LCD is absolutely correct. Saying that a device with an eInk screen will have better battery life than the exact same device with an LCD screen is absolutely correct. Saying that a DR1000 doesn't last as long as your cell phone is meaningless with regards to the benefits of eInk.
