I have a 2011 MBP that I use for music and video editing. It's a 2.0GHz i7 which I updated with 16GB of RAM and a 1 TB SSD. I primarily use it as a desktop Mac though connected to an external display. I've been waiting to see if a new Mac mini would come out but I'm not holding my breath. I have no use for the new touch strip so I've been looking at the base 13" model. Even though my current machine is 5+ years old, would it be a downgrade still to get the 2016 base model which is an i5? I mainly want to upgrade because my existing machine doesn't support 4K and I now use a 4K display.
