This. Is a great and lovely device, but for example in my case there is no need for it.
In my living room I have a TV connected to a MiniPC (before a laptop) and I use that for everyting. I mean, browsing in the net, listening or check youtube, mails, and also listening music and watching movies. I don't even use smart features from the TV since I prefer doing it through the computer with a wireless mouse and keyboard.
So I have the computer through a DAC through an amplifier to my speakers and is the center of everything I do when I want to relax or do stuff.
Remote control? No problem, I turn off the TV, the computer is always on 24/7, Tidal and spotify always open, I just open the apps from my phone and control from there. I can easily from other room select track, start, stop, or do whatever I want.
And the mini PC I have bought was cheaper than a Wiim device.
Again... context is everything, probably in a world where my living room won't have a TV, or TV will be in another place, and I just want to stream music, Wiim ultra will be my choice for sure.
Some day (When I dream) I would have in my living room my speakers just for music and a special room for home cinema with another kind of speakers and a projector probably, but meanwhile, the miniPC does everything I want.
