I think everyone is forgetting that Steve said he had concept/products in the pipeline for the next 10 years; it has not been 10 years since his passing. And for all we know, all of that stuff could have been shelved.
I am also wholly unimpressed with the current lineup of Mac hardware. New MacBook Pros are ok, they would have been even better had Apple included the latest nVidia kit instead of AMD, but power, yeah yeah whatever. iMac Pro has a decent spec, but can't be upgraded and you are basically tossing a kick ass monitor away when you get something new.
This is a pipe dream, but it would be an interesting test for Apple to sell a tower computer "DIY" that only had the Case, Motherboard and whatever "other" electronics such as the T2 chip, plus a USB installer stick; with the rest being able to be purchased as the user sees fit from wherever. Maybe sell one with a LG1151 and another with the LG2066. What a pipe dream; but even at a $1000 (almost double the cost of current case + MB), I would bet they would sell like hotcakes.
