I find the Raspberry Pi 3b+ still a good choice: it has enough power for many applications and works without silly connection adapters.
My problem is that Pimoroni, my regular supplier, immediately stopped selling the good old Raspberry Pi 3b+ as soon as the Raspberry Pi 4b came out.
I am not happy to must redesign my devices to cope with different connectors.
Am I the only one that still would buy a Raspberry Pi 3b+?
