"After the last few years, it's been made pretty clear Apple does the bare minimum on their hardware. What they do put in is quality, but if you want something extraordinary, you have to go modular and piece it together yourself."
refers to, which is Apple having shaved off every hardware feature possible down to a bare minimum, in the case of even their best selling computers, an integrated board, a battery, display, keyboard & pad, with none other bells & whistles that made the MacBook Pro popular in the first place. The only thing left they could still remove and get away with are the audio out jacks, and they've already warmed everyone up to that by eliminating it from iOS devices. They already tried going further and eliminated so many ports off the 2019 models they had to add them back in. But in each of the few hardware elements that remain, you will find a quality, reliable, standard item. A quality integrated chipset, normal display, keyboard and battery, and that's all you're getting. Don't expect them to start making 21:9 3d holographic displays with rocket launchers and all manner of cool features built in. They'd need to see their sales fall into a hole and get desperate to start taking unecessary risks like that. The large iMac should be a 34", but they'll choose it based on what display they can buy economically and at scale.
