Re: KaiOS - what I'd really like in a phone OS ...
What I'd really like in a phone that would allow me to dump iOS and Android (I run both as I'm a dev) is simple.
- 3G for calls and texts.
- Contacts, email, and MP3 player (as per a feature phone not an app store).
- Built-in apps for 2-factor auth and password management.
- All the above backing up as encrypted files (my passwords) to a folder in a major cloud provider.
- No app store, and no account needed on the phone other than for the previous item.
That setup would be pretty self-contained, do the minimum needed for my work (2-factor and passwords), avoid lock-in ('my' cloud storage), and be (relatively) proof against obsolescence for a fair few years.
