Your just have find out what the better part is . If you have a sufficient setup now, wait. I could not because my MBP was not cutting it for extended work from home. If it was not COVID times, and less home work, I would and could have waited.
Good for you. I had iPhone 6 till this year when I finally changed it for SE2. Couldn't be happier as I prefer touchID and overall its a great phone for awesome price.
I did check the iPhone Mini yesterday and to be honest I was impressed. It feels great in the hand. But because I'm like you and I keep my phone for a long time I think I will start to think about an upgrade probably 2023 or 2024 the earliest.
Part of me would love to get the Intel iMac and be done with the waiting but I really know I would regret that decision as soon as Apple showed us the AS iMac. Its tough spot to be in right now as the transition will take a while but buying Intel just doesn't feel right to me. Even though I would love to get a fast computer
Hahahahah, I'm so conflicted but the better part of me has to win
