@roguerascal With improvement to battery life, and availability questions (big ifs for now) -- a PinePhone running Mobian with convergence hub (dock) may be a solid bridge for 2 years to something to meet your complete priority list. Mobian is very stable overall and apps availability is good. A smaller set of apps work well on mobile screen, versus in docked "desktop" mode where display size is a non-issue. I have a longer review I can post but registered after seeing you post and don't know rules for long posts.
