Of course "Pro" doesn't necessarily mean "for people that use computers for a living", or in their professional life. That would be asinine. Pretty much every professional uses a computer is some fashion and computer needs for those jobs are almost as diverse as the jobs themselves.
Despite what some of the recent discussion has evolved into in this thread, the added "Pro" on Apple devices has always been there to distinguish multiple options and signify the one with the higher performance and/or larger number of supported features. In computers, this has always been clear. MacBooks and MacBook Airs were lower power/performance devises. The MacBook Pro was a significant step up in computing power. This is true of the Mac, with the iMac, Mac Pro and iMac Pro. Specifically, for Apple's desktop line, its meant Xeon class CPUs and ECC RAM. If Apple wants to make a top end, performance laptop, Xeon and ECC is now possible.
But hey, don't let me get in the way of you railing against the use of "Pro" term in a computer to somehow means professionals without high demand compute needs don't exist...
