My Xmas present to myself was a Galaxy Note 10.1. It just got updated to Jelly Bean, and on the Note it has a nifty multi window feature. It might take a little while to set it up, but now I can read a book that is 2/3 of the screen in landscape and have a dictionary or encyclopedia our perhaps map open in another window, I can have more than two open at the same time, but I haven't gotten that far yet. So far though it is very nice to be able to check something while reading and not really have to leave the book behind. If I was a student I could have a note app open, copy and paste text that I refer to in my notes etc.
This is all new but I can see some serious development potential, tapping on a word in the reading app and have it appear in the dictionary instantly, that sort of thing.
