The color Trion eink devices that are coming out are SLOW to update the screen and they are NOT 1600x1200 resolution. They are in fact 800x600 resolution. So the DPI is rather poor.
Ectaco has a bad habit of LYING (yes, that is the correct word) about the specifications of their devices. Yes, the B&W layer is 1600x1200. But when you add the Triton color layer on top, you need multiple pixels to generate the color. So that drops the effective resolution to 1600x1200. Now if Ectaco had gone with a large screen 1600x1200 B&W eink device, then they would be doing well. As it is, it's going to be slow and it's really only so-so.
