Great work. I believe used M1/M2 machines will be favored by young developers as their personal fun laptop in a few years, like the Thinkpad T420 used to be. For different reasons, of course.
Do the M4 and M5 GPUs also change a lot from the M3? I hope it's not too much work to get those going once M3 is usable.
I just like the build quality and they are reaching the 200€ threshold on the used market. I bought one with 16GB RAM and a small black strip one the side of the screen (don’t bother me) for 230€ last week
Public information seems to describe the M4 GPU as mostly a performance-oriented refresh of the one from M3. M5 has brought bigger changes, not least neural/tensor accelerators on chip.
