On the side note I must confess that it was my humorous take on the outrageous prices they're getting for a Raspberry PI 4 due to the world's inability to function anymore. ( A $ 50 PI is now around $ 150 and scarce. )
Raspberry Pi isn't the only low-power (such as Intel NUC) or SBC device (ODROID, Rock Pi, etc.) out there though. If you don't really need advantage of big community and guide/article dedicated to Raspberry Pi, other device should be better option.
