It's been a while since I read a hardback. The last was the John Peel auto/biography which I came across ridiculously cheap, I was waiting for it to be published in paperback, but couldn't resist it at the price I got. It was very heavy and big, not particularly comfortable reading, but looked great on the bookshelf. Otherwise I'd say about 95% of the books I read are paperback, purely down to being a skin-flint!
I confess that I haven't read the entire thread, being a newb to the forum and wanting to share my opinion. But I have seen a few mentions of Large Paperbacks, and wonder if there is really a demand for the huge "C" format paperbacks, which are usually the size and weight of a hardback, are they produced instead of a hardback? Otherwise I really see no point to them
