To be sure, I too prefer a book. But there are plenty of times I would love the option to reference a book at an inconvenient time (like when I'm at work 50 miles away). Having a low fidelity option is preferable over none at all in these cases.

Someday we'll have an honest-to-god book with e-ink, which will reconfigure itself to whatever we want to read and get the best of both worlds. (PopSci promised me this more than a decade ago and I'm bitter it hasn't happened yet!)
