Couldn't have said it any better.This simple definition is what makes people complaining about laptops needing all kinds of ridiculous specs to be considered "pro" so amusing.
Actually, it does. A professional is a professional. What makes a machine "pro" then? For the professionals who do 4K video work a machine with anything less than 16GB of RAM and a Quad core processor is not a professional machine. Meanwhile, back in 2013, my father was running PLCs for factory automation via VMs and remote desktops with a 2006/2007 White MacBook. The only thing without value here is trying to endlessly define standard that's different to different people.
