I realize how adaptable tablets and computers are and how much that they can do, but there are still reasons to use an eink device with your schools and textbooks. One big reason in the classroom would be battery life, that month on a charge ensures that the device will be working and then also if a students does stop it won't be all of them. For tablets, my worry about power would be for the teacher at the end of the day, if the students have been movie watching during lunch it could be quite possible for a good number of them to be it of charge by the end of the day. Then there is reading itself. There have been studies that have shown that reading with eink shows the same effects in the brain as reading from paper, but tablets are different, not necessarily bad, just different. Then too, that power issue come up again for extended reading, think an hour at a time. We want students to get into flow and close reading, and eink devices are good for that. Eink devices like the kindle, nook, kobo and others have the interaction abilities that we would like students to do too. They can still highlight text, take notes, use interactive dictionaries, and even go online (good for text but not much more). So don't give up yet on eink, it is still very effective. Perhaps the ideal student device would be both tablet and eink, such have been made before, but perhaps the tech wasn't yet up to the necessary levels. So hopefully companies are looking again to tie both together.
