They also had the V60C and V90C on hand. These 2 were just announced in the last few days, and they have the new color E-ink screen. These 2 should enter production in the next few months.
I did get a chance to go back to the Hanlin booth and shoot another video. Since I don't have any experience with their ereaders, I didn't do anything more than try to show you the refresh rate. If you can't see the color screen, try watching the video in HD. Apparently the colors get messed up when Youtube dowgrades the resolution.
