Some people on this forum and many other forums insist that the MacBook Pro 15 Retina is so great that many who have the MacBook Pro 17 won't miss the later if they upgrade. The common argument is that since the MBP 15 Retina have a much higher resolution the MBP 17, it would be much easier to see on the former even with the smaller screen. Well, I have the two side-by-side and I have to disagree, but let carry this logic further. The MBP 17 has a resolution of 1920 x 1200 and the iPhone 6/6S Plus has a resolution of 1920 x 1080. Follow the previous reasoning, it should be almost as easy to see on an iPhone 6 Plus screen as on a MBP 17 inch screen. This is absurd.
