I was given a Kindle Paperwhite for Christmas and they do have loads of advantages as already mentioned.

However, I do agree about the pleasure of turning pages, the smell of books, the variety & appeal of dust-jackets and of course, some beautiful illustrations which always appear better on paper (to me anyway).  I have some beautifully illustrated books which are a pleasure to browse through and I don't believe Kindle will ever replace those. 

I wait to be proved completely wrong of course
