We are in the process of switching out my work computer with a new M1 24" iMac. It is:
- 8-core CPU
- 8-core GPU
- 8GB RAM
- 256GB SSD
- Ethernet
- 10-key Magic Keyboard
- Yellow*
Since this iMac is replacing a POS terminal that is also my every-day work computer, it need not be fancy. I've been on a 2015 21.5" 4K since, well, 2015, and it has always been fine. So, the new thing will also be fine. FWIW, the 24" is about an inch wider overall, so you can take that into account if you are in a space-saving location.
* I don't care what Apple says, this thing is not yellow. It is gold!
