One of the core improvements over traditional books, is portability.

I can carry around 100s of books whenever I travel - without having suitcases packed with them.

To compare this with ebooks is pretty strange, considering the portability is 0. It's basically saying "you can have multiple books open at the same time which keep their reading position".

Great, you have multiple tabs in a browser open now - you've achieved it.
