Agreed. I read probably more than everyone else in my circle of friends/family (except for some in graduate school) and I love e-readers. I recently spent $5 more on a text book that came in Kindle format not because reselling books is so shitty now, but because I could easily browse notes/highlights and bookmarks.
A class I'm taking now required me to buy the specific texts because they would reference page numbers in the books. I'll tell you it's hard going back to paper. Some of them are printed on cheap paper and it dries your finger tips, ink rubs off on you, and then there's breaking in the new books so they're comfortable to hold and read.
