Wifi is working « fine » on my mac mini m1. A little bit less than my imac but it works 😉Coil whine has been noted as a mac studio issue but don’t forget the mini has well documented WiFi and Bluetooth radio issues too.
The pricing is set such that the mac studio looks an attractive upgrade for the people who can afford it.
I have no more bluetooth problems (i.e mouse cursor stuttering/jumping) since I unplugged one usb-a (the lefter one)
I prefer dealing with wifi and bluetooth than with a noisy mac studio as the computer is in ly living room.
