Agreeing on using the Windows interface from the couch is far from optimal. I am a big proponent of the "
10ft Interface" concept. Things should be simple and intuitive to use. Screen navigation with simple left/right/up/down controls and OK buttons. Extra metadata (album covers), descriptions, etc... delivered and presented in an organized fashion.
In fact, my first "streamers" were custom-built HTPC's I went from small factor Intel Atom/Ion build on mini-ITX Zotac board. Then it was a tiny Asus Eee-pc box with gen 2 of Ion on it. Several semi-custom ARM micro-pcs like Khadas-VIM. OS for these was OpecElec at first, later switched to its fork - LibreElec. Running Kodi on top of a thin OS layer. Then switched to Plex and realized that the streamer itself suddenly matters very little so I went with better long-term supported commercial streamers, like FireTV 4k and now Nvidia ShieldTV.
The last one is really great, and one really cool (maybe even killer) feature is AI upscaling. It is not simple video resizing and sharing. It's much more than that and my old 480p videos look brand new again.
As for Mark's remarks of limiting - I could see how some of the classical music sources are limited to in-browser streaming and never came out with Android/IOS apps - it's their loss really. This is a very old-fashioned way of doing things. Please keep in mind me saying this, and I'm far from a spring chicken - in my mid-40s and doing IT for over 20 years now.
