"Apple has always included plenty of ports in the pro models, and they will continue to do so..."
As long as you get to define "pro model" and "plenty of ports" then sure. We all know how SuperKendall would define these things.
Of course, the topic was Macs, not just Mac notebooks, and the current "Mac Pro" is the very definition of "not plenty of ports" unless all you want is USB and Thunderbolt. No PCIe slots, no drive bays, limited internal storage, no graphics upgradeability. It's a "pro model", though, so I'm sure you say it's "plenty". You have a long history of defining need by what Apple does.
"There's nothing wrong or odd about having multiple lines of product that serve the needs of different users."
No, except this isn't at all descriptive of Apple and their Mac line generally speaking.
