It’s pretty good for very early software. A bit more work and I’d probably use it.

Xfce. It does what I want it to do and little else.

Been pretty good. I only use a few of the things they provide but it’s all worked well. The android app is sort of janky because it’s mostly several other apps, but I don’t blame them for not developing a shiny app for their service.

Mostly I sync contacts, some nextcloud stuff, and use their XMPP server.

It’s doing fine? I don’t use their email so I can’t speak about that, but… Did you have any specific questions?
