@tante The interesting thing about your observation is convinience.
You don't have to buy a device that you have to assemble, setup with absolutely unfamiliar software and configure all the things your self.
Now they set up one or two user accounts and will be guided quite comfortably through the setup.
This reveals the weakness FOSS always had: the lack of user experience.
I don't like these agents, but I wish we get motivated by this to do better UX in FOSS.
