Hello everyone, I'm currently an undergraduate student and I was thinking of purchasing a new iPad for mostly using for reading textbooks and other PDF documents. I am currently carrying a lot of big, bulky textbooks around and I think it would be much better if I have them all in one place. I currently have a macbook pro (13", 2011 model) with a few PDF copies of a few of my textbooks but I find it to be a little hard to read on the computer screen. It also feels a little clunky to have my textbook + other things open on my computer all at once. My family owns an iPad 3 and an iPad 1. I love using these devices (but I find the 1 to be very clunky and slow these days, especially when opening big files). I like reading on the 3 and absolutely love the retina screen. I am currently considering an iPad 4 or an iPad mini. I really like the form factor of the Mini but I do not want to pay for the old technology of the non-retina screen. I also feel like the smaller screen may make it more difficult to read the textbooks. However, being just a student I find the cheaper price point of the Mini to be very enticing. Any other college students here use their iPad for textbooks? Mini or 4? Any refurb models for either one that can lower cost? Thanks!
