Yeah, now that we are a few days out from the release I'm having mixed feelings about upgrading.
I usually upgrade every other year, like clockwork, but as I was about to upgrade last year to a 15Pro, I had an incident with my 13Pro in which apple replaced the device. The replacement iPhone 13Pro was brand new with 100% battery, and I've been using it now for about a year. I couldn't justify upgrading from a new iPhone 13Pro to a 15Pro. Instead of being two years old (or three) the 13Pro is now a year old and has 92% battery health. So I'm probably just going to wait until next year.
For a new Apple Watch, on the other hand, I may go ahead and upgrade from my 7 to a 10 or a black ultra. I'm waiting to see some reviews and teardowns and for the first price reductions.
