I have different experience: it seems a trend that the books I'm interested in (note: not fiction) are first made for hardback, then just scaled down for paperback, resulting in pages that are too annoying to read. After a few paperbacks that I've hated, now if I see that the paperback has smaller dimensions but the same number of pages I am going to order hardback.
