I have a question concerning the screen resolutions on the various MacBook Pros and the Airs. I am 60 years old and wear glasses. I tried a 13" 2011 MacBook Air with the higher screen resolution. Everything was very sharp but smaller on the screen and harder for me to see. I went back to a standard resolution 13" MacBook pro and it works pretty well but I find myself scrolling more. Now getting to my question. Would there be any advantage in getting a 15" standard resolution screen over the 13" MacBook pro? Would it be any easier to see than the 13" and maybe less scrolling? Thanks in advance for anything you might be able to share with me.
