In the soon to be two years of USB C there is no steady market for the standard yet. Most CPUs skip performance boosts in order to make devices thinner, cooler and more efficient. It's too sad the battery power in the rMBP 2016 still suffers even though a new architecture has found it's way into the current generation. If you want bleeding edge, you have to go to the Dell XPS 15. The battery is not as strong as the rMBP 2015, but the power of Kaby Lake and Nvidia 1050 GTX is still lucrative for users who prefer power over battery life.
I believe you, but the IKEA catalog is in fact not even photographs anymore. They tried to use real photographs after moving to CGI, but the feedback was negative, and the next year they went back to 3D modeling. My comment was not targeting wedding snappers. I don't even consider them photographers. If you do the entire process yourself, you are no longer a photographer. You provide a wide range of services rather than framing the world to your taste. The same goes for catalog people. They work in marketing, not photography, even though they have Hasselblad or Leica S.
