It is definitely good for reading papers, but I think its pretty difficult to read a whole school book on there! I have two books that are over a thousand pages long- and when I look at them on my pc I can skip to chapters with ease.
I haven't tried any because I think webOS has a very good one. I have been using it to read papers for school and I think it's very good. Have you tried the one in webOS?
On the Web OS I have to scroll through a ton of page numbers to get to it.
I was hoping there was a better alternative with android. =[
