Why aren't e-textbooks selling?

<p>My 2 HS students weren't issued science textbooks this year. Instead, they received a password for an online textbook.</p>

<p>H and I have found it much harder to work with -- especially when trying to answer a specific question. Flipping through a chapter or section, skimming quickly, is so much easier with paper books. Also, 2 people can look at a paper page at the same time while sitting at a table. Swiveling the laptop is much more cumbersome.</p>
