I have played with the newer MacBooks at Best Buy and what I hate is that one needs an adaptor just to have access to standard USB! That means out of the box I cannot sync my iPhone without an adaptor! How absurd! I do not plan to upgrade my 2012 MacBook since it does everything I need, but one day it will break and require that I move to a newer MacBook. My MacBook has ethernet, Firewire 800 and a SD card reader which I also see are lacking in the newer MacBooks. Why? What of those working in office environments where WIFI is not fast enough or does not work well? Why eliminate the ethernet port? Why eliminate the SD card reader?
