Oh I'm screwed. I'm fully in on Apple Photos, Music, Calendars, Notes, the lot. I will pull things out carefully one service at a time over the space of a few months or I'll get pissed off and give up.
One thing I am looking forward to is a keyboard that isn't shit.
I have a 14" M1 MacBook Pro. The keyboard is "ok" but not great. It occasionally misses keypresses when I'm typing fast or hit the edge of a key.
Also I never really got on with the keyboard layout. Some things are just better on other platforms like position of hash, usage of meta-keys and discoverability. I find, despite rarely using it, that I can navigate around windows 10 better on a keyboard than I can on a mac.
I mostly use my mac in "desktop mode" with an Apple studio display (that's the most difficult thing to give up) and a TKL Durgod K320 cherry MX red mechanical keyboard so I will reuse the keyboard for "the other platform"
Build quality on non-Apple machines have been rough for me. I burned through both an XPS 15 (caseflex causes restarts with keyboard use) and a Framework (random restarts, never could pin down the hardware issue even with mainboard replacement). The I've settled on a good ThinkPad and, honestly, I set the power settings simple and just keep it in a docked state. Never even think about it!
Yeah I have owned a few thinkpads. I went for a desktop because I am totally fucking done with owning laptops now. I don't need one so I'm not bothering any more.
