Re: Joshing or not - I couldn't tell
I'm retired, but not (quite) as old as ken. Maybe it isn't quite a joke - I use an iMac and iPad for most day-to-day stuff, and have 3 RPs: An original Pi; a 2GB Pi4; and a Pi Zero 2W which are for background use and fun. I refer to the newer ones as my "server farm".
If you don't mind the lack of ports, the pi Zero is "astonishing". I originally used it as a Pi-hole but now it's for casual development work - A rough calculation indicates that its VAX MIPS/VUP performance is nominally ~5,000 times that of a 11/750 that I used in the 1980s. A multiuser web/database test with Bullseye 64 bit Light and a SQLite database on a microSD card gave ~14 inserts+70 updates/second.
I still run Windows XP and 10 in Parallels on the iMac to run stuff that I wrote before I retired, but if I replace the Mac they won't be installed.
