It's...okay. The hardware is decent, but the software (particularly the iOS app) has always been terrible.

I'm going the nostalgia route and playing Bioshock

Pi-hole at home and pi-hole+PiVPN while away. Works perfectly

It’s top on my list of Chromium browsers

Ironic…

Prepare to be continually disappointed. I switched my domain over when it was first announced, and although it certainly works, there are definitely some needed features lacking. Other than centralizing how emails are delivered, there isn't much of a benefit to using a custom email domain. Plus, I've yet to find an iOS app (other than Mail) that works with them.

Regarding migration, have you tried simply dragging and dropping the email from the old account onto the new one? I haven't used T-bird for this, but it works in Mail.

Hmm, I tried Arc but didn’t really “get” it. Perhaps I should give it a longer try

I get people wanting an alternative Chromium based browser. Vivaldi, IMO, is a much better than Brave, and doesn't have all the annoying crypto weirdness.

I don't use either, though, I use Firefox

I used both a Magic Mouse and Magic Trackpad and much prefer the trackpad. I can’t work with multitouch gestures, and I’ve never had any wrist pain after using it all day.

Yes, it works just fine, just make sure you heed the backup instructions (like with any online account like this) if you are worried.

It seems like a simple thing, but I was really looking forward to that feature as well

Apple Music. I have a very large library and am an album listener. AM is much better at library organization for me.
