I'm going to be using this to read technical books, a lot of which can cost between $50 to $100. Compared to the cost of my library, I think $500 is easily worth it for being able to take most of these books with me anywhere I go.
But how much do the PDF versions of the technical books cost ? And where do you get them? I am also trying to calculate the costs and see if I can throw the bookshelf away.
