What made the MB "Pro", if memory serves right, it was filled with components that represented the state of the art when it was released. Best screen, latest generation of CPU, PCIe SSDs, etc... The best you could possibly get, in a sturdy, well designed machine, coming with an OS that just works.
In 2013, some company even found that the best performing Windows laptop was a MBP (!). [1]
> People complain about 16GB RAM. Does your current MPB has more?
That's the point - the new generation should allow for more than previous. Why would be your motivation for purchase, to get exactly the same thing you have now?
