I really dont see the appeal personally of these Kindle or Ebooks, the only digitalised book i read recently was one of the classics on my "100 Classic Collection" game for DS! I much prefer the classic paperback book to squinting at an electronic screen and the old fashioned book will never be replaced totally.
For a certain type of person I can see this being true but consider the following:
1. People are living in smaller spaces.
2. The cost of ebooks is likely to go down while the cost of 'real' books has been increasing.
3. People travel.
4. Ebooks allow you to access foreign language books easily.
I love to travel. Last summer I took 20 books with me on a 4 weeks trip. You try carrying 20 books with you (I was discarding as I went). This past weekend I took 4 books along with me on a long weekend. If I'd had a kindle or similar I could have just carried the one, light weight thing.
If I want to buy English language books I either have to pay expensive, imported, prices or pay expensive postage. With an eReader I can download at the click of a button. I'm sure other people have similar experiences in different languages.
I love books. But I do think they'll eventually be replaced.
And you know what, I don't care all that much. The beauty of the story is still the same, regardless of the medium.
