For the record I definitely don't like apple... but I'm also pragmatic and just want stuff to work.
Yeah definitely, it takes a bit to figure out how to "get around" on each device, and even model to model, I pick up and Iphone 6 or a pixel and it takes me a bit to remember how to do stuff.
There are a number of different issues that I deal with a lot but for me the most annoying is the app integration on the android products. For instance if you're using various ESRI mapping products and you want driving directions to a point on the map you can just click/tap and hold and then you get a prompt to route to that point. Can't do that with other devices.
Also copy/pasting doesn't seem to work as well, folks seem to struggle more using OnX on non IOS devices.
My buddies garmin doesn't pair as easy with his samsung as mine does with my Iphone.
And then all the IOS specific things like Imessage, air drop, bumping wifi passwords, etc. None are dealbreakers and all are obvious attempts to keep people in the Iphone club... but also it's nice to be able to share 150 full res photos with my buddy after a trip, currently to keep the resolution I have to send them via WhatsAPP like 10 or 20 at a time... which is super annoying, or create a google photo group album. Again not a dealbreaker but also annoying.
Also the Iphone and ear pod game is unmatched in my opinion.
