This tiny computer changes EVERYTHING (youtube.com)
CM5. 2gig $45, 4gig $55, 8gb $75.
RPi's iO board has a power button. Nice. I have to hold down the power button for like 10 seconds to get my stupid Thinkpad to hard boot, and even then I'm not sure it really boots off.
You can build timeservers on it, with ptp hardware timestamping, to serve ptp and ntp. ... It will do 3k on a large commercial display screen.
There are tons of sbc module makers now (and some like Radxa are faster than the Pi), because of their lack of supply during the pandemic measures. Pi still has the best support and community though, so you can more easily use them.
