I think everyone appreciates the advantages of paper books.
The feel and smell of the things is clearly a sensual pleasure, which I shall continue to enjoy.
However, it's a pleasure that I don't need to experience every day, or every time I want to read.
An E-reader has its own advantages, many of which have already been mentioned.
Someone spoke, I think, of reading in bed, where leaving the light off is necessary if you don't want to keep your partner awake.
The other advantage in this situation is the lightness of a kindle or tablet. Holding up a large book, like the Lord of the Rings, while reading in a horizontal position can be weary work, often giving you aching arms, just before sleeping.
But the big advantage for me is that I can easily order books in English from my home in France, which is impossible with paper.
Any book I like enough I can buy on my next trip home to see the family, to add to my bookshelf for a future rereading indulgence, if I wish.
So I say, both formats have their place.
