There are no two ways about it: E-books are here to stay. Unless something as remarkable as Japan's reversion to the sword occurs, digital books are the 21st century successor to print. And yet the e-book is fundamentally flawed. There are some aspects to print book culture that e-books can't replicate (at least not easily) -- yet. Let's put this into some context first. Amazon sparked the e-reader revolution with the first Kindle a mere three-and-a-half years ago, and it now already sells more e-books than all print books combined.
