I interpret this as a phone that can do the basics like agenda and such, but does them in an unintrusive way, and givesyou full control over when and how it's allowed to interrupt you. If so, that would definitely change the dynamics between me and my phone. Basically all apps on ios / android (modulo some positive exceptions) are out to grab my attention all the time, and the OSs make it quite hard to really control that. I guess that would be more sustainable than trying to disconnect entirely.

Besides this, the link here is actually the OS, so this is actually OT.
