I do buy other devices. I have an iPhone as my daily driver but also an android phone. I used android for 2.5 years as my daily driver before I came back to the iPhone in 2014 so if I wanted to I could easily pick up on android again.It appears you have made many of the same mistakes I myself made i.e. getting to deep into the Apple eco system.
I saw a few years back where this was leading and so bit the bullet and started to cast my net wider e.g. bought a couple of Chromecast, purchased some movies from Google Play, bought an Android phone as well as my iPhone and built a high spec Windows 10 PC.
Never again will I put all my eggs in one basket. This has given me a much wider range of options and prices.
Everyone makes their own choices but I do think it a mistake to limit your options.
I like trying out new things, outside of Apple’s ecosystem which is why I have other devices. They don’t quite do what I need so they don’t replace my Apple ones as primary devices. However I’m not afraid of trying new things.
However you won’t get me to try another windows machine.
