In my experience very varied. I feel students lean more towards Android, but if you develop on Mac you’re also more likely to have an iPhone, but the one place where it’s somehow been consistently Android in my team is the app developers.
While I don’t mind it at all, somehow the Android build of our app still has the most issues. Consistently over almost six years now. Which I find a bit ironic.
A friend of mine that was also a former colleague has always been an Android guy. A year ago he switched employer and the new company is iPhone only - but he can’t get the latest versions, and it’s basically just the base version too. So he’s still running with his Galaxy S21, but no e-mail or calendar sync.
I think he’d switch if he could put some of his own cash in and upgrade to the top model.
People can have the preference they want in life, but there’s no need to obnoxious about it.
