Bluetooth is the gift that keeps on giving. Not sure why my Ubuntu insists on enabling it on every boot, at least on my hardware.
Good thing PC peripherals moved away from this junk. It was fascinating watching Logitech sell 300 euro BT keyboard with literally a second of lag, or "high end" mice with 500ms or more.
Hell, I barely use my PS5 controller because it sucks ass compared to my old Xbox 360 pad. Lag, lag, lag. 8 guess the majority does not notice or care, though.
