I have a couple pi’s that I use for a few different things.
a 0w runs piVPN. a 3b runs a couple curl scripts to poll my CPAP machine every 30 min and update my data on a dashboard and OSCAR. a pi4 has two SDR’s that I use for ADSB and monitoring my water service meter, my gas service meter, and my electric service meter. another pi4 has two SDRs that I use one for general fucking around, and the other used to pull data from NOAA/METEOR satellites (USG recently decomissioned some functions on the POES satellites) so I am repurposing this to pull GOES data instead. It also has a wifi dongle that is capable of packet injection which i use to deauth the asshole a couple doors down whenever i get bored (his truck is rife with FJB, fuck Beto, fuck your feelings, and maga stickers, so he deserves it more often than I get around to it frankly)
I use them because they are low power enough that im ok with leaving them running perpetually. I purchased the 0w, and one of the pi4s, the others were given to me by someone cleaning out some storage. I have no need for the GPIO functions, and frankly a ten year old dell thin client would have more horsepower and better USB bus capabilities (i have a few ancient thin clients too, doing various crap) not to mention running x86 linux which is a whole headache you dont have to deal with running ARM crap.
Ill never buy another one, microcontrollers have better GPIO options and if I want a small form factor for general computing Ill just get a ten year old NUC or a thin client and be done with it.
