I call B.S.: I've used those "toys for solo tinkering" in production control, monitoring, and data collection/communications applications in industrial, energy, and manufacturing settings. Sounds like you just don't know how to set up and build non-obese software. N.B.: An 8GB rPi 4/CM4 has more memory, more storage, more compute power, and faster networking and i/o than a Cray supercomputer had in the early 90s! It's a real computer. If you can't do most of the useful jobs on the planet with that level of performance, then you just suck at software. (Yes, I know most Linux distros are Jabba-level obese these days, but still...) Full disclosure: I have a PiBox on order, and will be prototyping a prepackaged server with it, which may well turn into a product itself.
