Luckily, I’m down to just an iPhone.
I used to use iPad Minis, but I was otherwise more of a Windows guy until 2022.
The only other kind of Apple thing I have is a GPU-accelerated Hackintosh running under KVM, which mostly gets used for adding non-streaming songs to my Apple Music library these days. I do plan to quit Apple Music eventually - I’ve been collecting and ripping CDs by TMBG, which is mostly what I listen to anyway.
You can self-sign and self-enroll secure boot keys. Can’t say it’s an easy process, though - I had a lot of misery with it on my Surface Go 1st Gen. Might be better on my Thinkpad.
