Comfortable reading size

There is this new trend to make books in what they call a comfortable reading size. It's slightly taller then a traditional mass market (about an inch), there is a bit more space between the sentences, and they run right to the edges of the pages. They also use thinner paper for everything (including the cover) and just don't hold up like mass market paperbacks. On top of all that they don't fit on the displays at work and it's awkward on my shelves at home. Oh I almost forgot to mention that they cost more too. I don't care for them. Mind you it doesn't keep me from buying them because I know the stories are mostly likely not going to be released into regular paperback.
