I love iBooks but nothing beats the durability of a real book. As great as it is to carry around my e-book library on my iPad, it can never compare to the feel of picking up a real book and flipping through it. That's a physical experience sorely lacking on all e-book readers.
So, can the real world feel of a book be duplicated electronically?
Perhaps.. one day... probably. The key is that a digital book would have to feel like a real book. One way to do this is with a digital book made of pages where each is a thin, flexible film, like e-paper, that feel like real pages.
Imagine an e-book full of a couple hundred blank pages made of thin, bendable computer displays. You'd select which book to load and each e-page would display a page of your book. You'd be reading e-ink text on real pages that you could flip through, highlight, take notes, etc.; much like iBooks or Kindle. Just don't dog-ear a page. For books longer than 200 pages, you could just cycle back – page 201 would appear on page one and so on. Now that would be best of both worlds.
