I've never understood who the "pro user" is other than those who Apple push to use the iPhone camera for video. I've always bought the "pro" line for increased quality components. I don't need to shoot Hollywood films on my phone. So I think instead of upgrading every 2 yrs I'll spread it out more. My 12 pro and 12 mini are still like brand new and will last until I'm bored enough to get something new.
I've chased Apple technology since the original Mac in 1984 (I still have mine as well as the original Apple Mac laptop). I don't see the urgency to do so anymore since there hasn't been much innovation lately. ( I do have new M1 iMac, iPads and 14"MBP) so that will hold me over for quite some time. However, I may bite for the new MBA M2 just because.
