The engineers at my old company utilized many of them to runs tests against hardware. Hobbyists don't realize that they can indeed have business uses.

My point is, a home server is not a main computer. I have several Pi's but never used one as my main computer.

I still have the dream that I can use a Pi as my main desktop and main laptop. I still need more CPU/GPU power and more connections, so the dream is not here yet. It will come some day. My main desktop now is an AMD A8 from 2015, which suits me just fine. My laptop has a Celeron from 2015, which is too weak for me. I would desire to have something like that AMD A8, but smaller, cheaper and lower power consumption. It will get there.

I've never used a laptop as my main computer. That doesn't mean other people can't do it.
