Apple released iOS 15 and iPadOS 15 on Monday, September 20, and, as usual, many people updated their iPhones, iPads, and iPod touches to the new operating systems. But unlike in the past, Apple is not pushing people to make the upgrade. For the first time, Apple is going to maintain the previous operating system for users who don’t want to upgrade. You can choose to remain on iOS 14, and still get essential security updates, if you’d rather not move to iOS 15. (When I mention iOS in this article, I also include iPadOS.)

In general, the uptake is pretty quick, but after two days, it seems that iOS 15 adoption is much lower than for iOS 14.
