I have no experience with my phone, tablet or watch slowing down. Getting major os updates is a major thing for me. It may not be for everyone, but I appreciate their attempt to update devices until they can’t. As for the price, my iPhone 12 was $700. Cheaper than my wife’s Samsung note and slightly cheaper than my galaxy s8.
I do like their ux on mobile. I have qualms with how restricted my iPad Pro is at times but it is easy to use.
Having languished for years hoping for new updates of android and being hampered by carriers or phone makers, I greatly enjoy the long term support apple gives to its devices.
On then computer front I’m a huge fan of Linux distros. If I could I’d move on from windows.
iOS requires WebKit based browsers no matter what they’re named. May as well use safari and its extensions until they open up the backend.
