Most, if not all, of my devices have a mobile app of some sort, but I don't always use them. I never use the mobile apps for my TV, fire stick, AVR etc. As daft as it sounds I like to be able to control devices without having to always look at a screen and being able to start, skip, pause, or restart a track with a physical button is sometimes more convenient and the buttons are always in the same place. It also has voice control which may be useful.This is an honest question and not meant to be inflammatory at all. What do you use the remote for exactly?
Everyone in my family uses Alexa to control the WiiM (they don't know or care what "bit perfect" is) and when I listen myself I simply use a mobile app. I really can't imagine why I'd ever want a physical remote for the WiiM itself. What am I missing?
Another factor may be that one of it's main rivals seems to be the Cambridge Audio MXN10 which has no remote control and I've seen a few complaints about the lack thereof.
All that being said I'm still not sure whether I'll be getting one and it clearly is not for you. If it was included it would up the price, obviously, and you would then be paying for something of no use to you, so it's a sound approach from Wiim I think.
