And I have no idea whether these book readers use uncommon or rare materials - trees are self-replenishing (when done right).
Don't forget, e-book readers, like other computers, can also be recycled and their components largely reused. Obviously, if the technology and SW becomes more standardized, we should see readers with even longer lifespans.
