You mention iPhone upgrades, so I was wondering how often people here upgrade their iPhones.
I typically upgrade every 4 years. I currently own the iPhone 13 Pro so might look to upgrading later this year when the 17 comes out.
There really is no problem with the 13 Pro though, so it will require some thought. I keep it under monthly AppleCare+. Sometimes I think about more Apple Intelligence features with newer models. On the other hand, they seem a bit underwhelming at the moment.
And speaking of tariffs, since I live in Japan, I wonder if tariffs would impact the pricing here. Apple seems to base their prices here on (1) the base price in the U.S. and (2) the current yen/dollar exchange rate. I would hope if there are unfair tariffs on the U.S. size that they would rethink that strategy for worldwide pricing. From your regional chart it looks like revenue from all the Americas accounts for less than 1/2 of total revenues.
