There are fewer and fewer reasons to buy new PC hardware as the decades have marched on. CPUs and GPUs have been overpowered for all but niche markets - and yes, gaming is a niche market. I've been averaging 7 years or more for my machines for a long time now; that was bound to show up in PC sales at some point. And i think people are still failing to account for just how muc mobile has utterly taken over most normal…
If Apple provided a way to use Mac minis to serve as distributed compile caching and distributed build tool, I'd have a reason to buy some.
Also, mac minis are expensive when compared with other miniPCs in the market. There are some ryzen5/core i5 systems with 16 and 32GB of RAM shipping with Windows 11 being sold right now on Amazon for 300-500€. If all you want to do is run stuff in a browser and do work then you'd be hard pressed to find a reason to buy a Mac mini, let alone a Mac studio.
