I feel like this is one area where the Tim Cook era diverged from Steve's ideology a bit. Prior to Steve's death Apple was more likely to not be the first to market, but the first to do it "right" once they did enter the market. Or at least in the case of the iPhone, they only entered once it could be done well enough. But the trashcan Mac Pro was just too ahead of it's time, and same with the 2016-2019 macbook Pro's where Intel couldn't provide a cool enough running chip, but Apple moved forward anyways with a bad thermal design for the power they needed. The technology is here now to effectively do those things, but it just wasn't back when they did it. If they brought back the TrashCan design, with accessible M.2 slots you could add, I'd buy one in a heartbeat (assuming it didn't start at $7000 F'ing dollars like the Mac Pro did...) I wanted a Mac Pro so bad when they announced it, but the price was just a hard pass for what it provided at the base entry.
The Mac Studio really needs a standard M.2 slot in it, and an easier way to take it apart just to clean dust out. The TrashCan design made that super easy.
