I think Amazon are over hyping the success of the Kindle.
I think e books will have a place.
But I think printed books will be around for along time.
Years ago they said that birthday cards would go out of existence due to e-cards!
Who sends an ecard these days?
Can you imagine giving someone an Kindle book fro Xmas ?
I think book sales are slow because everyone has books to sell.
And look at all the book sale fairs and the books in the Charity shops etc.
