Ease of use for non-tech people?

How would you rate the ease of use for non-tech people? I want to move my family’s emails over to V2 when it comes out, but some are less tech savvy than others. I have a minor in CS so I feel confident about my ability. I understand there are trades off as Helm evolves from startup stage and it’s also the price you pay to get off big tech, but want to make sure it’s not too inconvenient before migrating everyone.

Basic functions concerned about are email, calendars and sharing of them, and file share. Devices are PCs and iPhones.
