Exception, also it’s a small mouse targeted to laptop users., the same goes for R.A.T. M. Contrary to what you may think size matters when it comes to computer mouses (or is it “mice”?).

You’re right, I didn’t look into it close enough. But what difference does it make? An Xbox One controller can be used with a PC through a simple USB cable. I think I have six of those floating around thanks to being packed with a wide variety of devices over the years.
I think that’s a much more elegant solution than releasing a wireless dongle or changing the standard to something like Bluetooth.
