Before the release of iPad Pro, I always wish that my iPad Air 2 screen is bigger. Since the second iPad came out in 2012, I have almost exclusively used the iPad to read PDF articles and books and I really enjoyed it. The iPad has certainly brought me a lot convenience that I could never had before. Yet, I always wish the screen is a little bigger, at least like an A4 size paper. Now come the iPad Pro, and I was very trilled when I got my first one on the day it was release. I told myself, finally! After almost a week of trying, I am not sure anymore if the size of the iPad Pro is best for reading? I noticed that my eyes are not as comfortable as on the iPad Air 2. The wordings are smaller on the iPad Air 2, yet it seems more comfortable to my eyes. I can't explain why. May be it is due to the lighting. The Pro's screen is bigger therefore more light are going into the eyes and making it relatively uncomfortable. Or may the eyes are staring at the bigger screen and making it tired...I just don't know anymore. Holding the Pro is not uncomfortable to me, it wasn't heavy after all. However, I definitely miss the even lighter iPad Air 2. What do you guys think?
