I need the help of the readers in the room! There are very few, if any, threads about this. So what do you all use? I'm a frequent reader who is usually between 3-6 books at any given time. I also have a lot of [black and white] PDFs and ebooks to go through. What would you choose? I don't need another laptop. The kindle is easiest on the eyes from what I hear. It's also only $179.
