I’m using Ubuntu/Gnome/Wayland on the lenovo tp tablet x1 and very happy overall. Mostly using it for browsing, zotero, xournal++ and almost everything works out of the box and very snappy. Not at the level of win or ipad but can do everything I need.

I fully agree. User accounts should be separate and content should not automatically be hosted on all linked instances. It’s not scalable and will only lead to endless defederations.
