I think you (and users like you) are simply not the target customer for Apple anymore. They used to aim for the professional market segment, where people are using multiple displays, need external GPU for creative work and other external gear, and computers that don't throttle their CPU that easily.

But if the last few years of Apple's new hardware is telling us anything, is that Apple is now strictly casual-oriented, and if you're in any capacity a professional, you need to start thinking about getting a PC again.
