I think that the word-count of a book should be about how many words and author feels they need to tell their story. I don't mind big books, but to cram them with small font sucks. I wish they would keep the books at $7.99 and then when a big one comes along keep the font the same size, but ask $8.99 for it to cover the added cost. I'd pay an extra dollar not to have to read tiny font.
eBooks!
The real losers in hardcopy are those of us with less than perfect vision. The new fonts are not only small, but they are "light" (thin lined, I suspect to save on ink), and very hard to read.
Again, I say eBooks. You can make the font larger so you can see properly for reading.
