Yep, I'm in this boat. After years of macs my next will be a FreeBSD Desktop.
edit: Although phone is much harder. I guess I'll just turn all the 'stuff' like icloud off, use only signal and my banking/etc apps, and get a separate camera.. Anyone found a less painful way to live without an iPhone/Android?
As someone who had been in the Apple ecosystem since Windows XP, it was difficult to lose that constant seamless interplay between my phone and computer. But honestly? The trade-off was worth it in the end. I’m 8mo into Linux-only desktop and man…it’s great.
GrapheneOS is not quite "without" Android but it's without what makes it bad (Google) and works fine for me. I hear LineageOS is ok too.
