All true, but let's not accept the false premise going around that the Pro is a kind of humanitarian exception being generously administered by Apple for those who truly need it, a system that you're abusing if you expect PCI slots without being able to prove that they're strictly necessary for your work. "Admit it, you could probably get by with a performance-choked video card in an expensive eGPU bay squatting next to your $2000 Mac Mini if you really wanted to. You just aren't trying hard enough. If you really loved Apple you'd just do it and you wouldn't complain."
