slashgear has a
video of TI OMAP4 driving an e-ink reader.
The chipset is great in terms of power efficiency and performance.
The OMAP4 has an integrated display controller, and it's amazing to see what even current generation e-ink can do in terms of refresh once you eliminate the controller bottleneck.
Even if my money is on tegra2/PixelQi and Mirasol, e-ink could still be a player here.
This year we will finally be able to achieve all-day computing battery life on everyday devices.

Once you reach 8-12h, battery becomes a secondary concern for many people.
I'm also perfectly okay with tegra and OMAP and a linux OS for tablets/readers/smartphones. Now that google has finally decided to go to war and enable multitouch, things will get really really interesting.
I think Microsoft needs to adapt its interface, and it's gonna take the some time. No windows for me thank you.
