Linux is the third option. As far as many normies are concerned the second option is macOS
There are "servers" on Matrix. They are called communities
Here is the relevant part of the documentation for that: https://matrix.org/docs/communities/getting-started/
I have used Teufel devices in the past and they worked well enough. But I have since switched to a selfhosted alternative. Stupid speakers (in my case old 2nd hand stereo systems), raspberry pis and the Lyrion Music Server.
You get all the benefits of commercial internet enabled speakers (the project used to power Logitechs speakers before they open sourced it) including multi room audio, various streaming service integration (both Spotify and Qobuz are supported among others) and solid app support as well as the privacy that comes from not relying on an external server
The selection prompt exist. It's just implemented in a way that's less than ideal. On first start a popup appears informing you about the existence of other UI layouts.
There are just two problems with it:
- you can't actually set the UI in the pop-up. Instead you have to click a link in the pop-up which takes you to the corresponding settings page.
- the prompt shows up after the UI has already loaded. So it doesn't read as helpful at first glance. To most people, it seems to be an annoying pop-up that keeps you from accessing the app, that you can already clearly see in the background, instead. So they close it without reading it.
Fun fact: the train pictured here is a Siemens Velaro. That's the same family of train as the ICE.
It's the American Pioneer Edition, the variant for the American market, set to operate Brightline West services, but even that one is based on Velaro Novo, a platform designed 100% in Germany.
Edit: Velaro Novo for comparison:
That's how you get a Boing
One thing to make your girlfriend's transition easier: you can reconfigure the UI to be more similar to more recent versions of MS office. The first time you open it, there will be a popup that brings you directly to the relevant settings menu. It's not one to one but the major options are going to be in similar places after you changed the UI.
There used to be a Kodi/XMBC skin for that but development on that seems to have been abandoned years ago.
Depending on your use case Kodi might be a better fit for your HTPC as it tightly integrates with Jellyfin and also has a Spotify plugin. And some skins work generally the way the xmb used to work - they just look very different
