Dang fisheye lenses!
I was sure this unit was bigger than the Sony. Sure looked like it.

If anything I this demonstration unit does a good job showing how efficient e-ink screens are at power consumption.
Actually I think the efficiency come more from a different computing management. The Sony, when in waiting mode, still uses power. Proof is that even if you don't use it, you still have to recharge every 3 weeks, and it has nothing to do with the screen.
Speculation: If a device were to use flash ROM (if they exist
), you could go by without always rebooting, so the unit could go to sleep after every page turn. That would be a fantastic way to go. I'm looking forward to the day when they stop using traditional CPUs. Flash memory is the way to go.
