There are some similar boards with 3x6 layouts - ffkb and vulpes majora, both by fingerpunch, support 3x6 with a center trackball. I do miss the extra keys a bit with 3x5 layouts - when I eventually design my own board I think I’m going to do a 40 key layout.

Backups. Cloud services like Backblaze B2 are so cheap for the durability they offer, it just doesn’t make sense for me to roll my own offsite solution with a Raspberry Pi at my parents’ house or something. Restic encrypts everything before it leaves my machine.

Password manager- it’s too important and it’s the thing that has to work for me to recover when I break something else. I’m happy to support Bitwarden with a few bucks a year.

Email- again, it’s mission critical and I have a habit of tinkering with things and breaking them. And it’s just no fun. The less I need to think about email, the happier I am.
