I think the main thing comes from this point: > however, I only maintain 1 calendar / todo (my work calendar). What I've found, personally, is that having multiple e-mails is fine. I don't need to check them every five minutes anyway. But I don't want to have my work anything on my personal phone (because I don't want it remotely managed), nor my personal stuff on my work email (say I need to schedule an interview for a new job). I'm sure quite a lot of people are in the same situation. My personal best experience was when I was using a personal mac for work, and I could have all my calendars combined in basic macOS calendar app, and emails in the mail app. Everything worked so well, and it's something I miss terribly since I've moved to Linux.
