Yeah, iRex did the same thing with the DR by optimizing a lot of the way the driver works. Still, of the 0.85s refresh rate people are talking about with the DR, 0.80s of that is the eInk.
Older devices usually had a 1.0s or higher refresh rate, and a lot of that was due to slow drivers (.80 for the eInk plus .20 - .50 for the driver). That's what they're comparing the PRS-700 to when they say that it's much faster. The same is true for the DR.
You can do a lot of optimizing (.05 with the newer drivers), but you're not going to make a huge difference, no matter how much hype there is about a new device, until eInk technology improves. Every device is still based off of a 0.80s vizplex eInk screen, including the PRS-700.
