I would say that completely FOSS Linux OS won’t ever be as smooth experience as business solution. Jolla has developed SailfishOS which is mostly open decade now and it is quite stable. Also has android emulator where you can use most android apps, but not all. In my opinion we should support that as much as possible to have true alternative. Also EU should start supporting ita development

I would never recommend bambu products or to install any bambu software. One of our company employees installed bambu studio (for personal needs) and it started immediately to send data to 7 ip addresses which all were linked to malware. Buy Prusa if you want to own your device actually.

I would give vote for Prusa Core one. Not the cheapest but great support and very reliable work horse. Currently only option is MMU3 but they have announced that they are working new solution
