With iOS 26 you can now export Apple notes to markdown as well, which I've done recently on the beta and put them in my Obsidian folder.

The switching cost for me is more so the stupid little conveniences I'm not quite willing to give up yet. I do regularly take advantage of clipboard sharing, universal control, AirPods device switching, auto-fill from messages & mail for TOTP (which works in Chrome now on macOS 26), and my Apple Watch has been hard to replace last time I tried (was with a pixel watch 2, maybe the 4 will be good enough this time).

I can recreate some of that with KDE Connect & Linux, but last time I tried it wasn't nearly as seamless.

Photos are the most important to me, and I already have those regularly backed up locally.

I suspect I'll switch eventually, I just have to mourn the loss of the little things.
