Books Are Forever

For a while now, I've been worried that the book, the physical printed book, was going to disappear. I use kindle and its perfectly adequate, but books are the bee's knees. I am, therefore, heartened by this from Megan McArdle:

I'm pretty sure the print book's days are numbered for anything except specialty applications.  The die-hards will cling for a while, but ultimately, book buyers are already an extremely affluent group, and the convenience in acquiring, porting, and storing your library simply overwhelms the drawbacks, especially as Amazon has introduced innovations like eBook lending.

Inasmuch as she is wrong about everything it follows that she is wrong about this. For my money, if you want to know, the book's future lies in ondemand printing services like the Espresso ondeman book making machine.
