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.

That’s considerably worse than most people experience - keyboard latency is normally under 15ms - and I think that’s part of the problem there: if you live somewhere with a lot of congestion from other devices, poorly shielded microwave ovens, etc. you have a legitimately terrible experience but it’s not common enough for it to actually get fixed since it doesn’t impact sales.

  Pretty sure you have forgotten or never experienced the awful bt devices from 15 years ago. Or maybe latency is not a big issue for you.

    Latency is something I notice, but having used Bluetooth since it first came out, 500+ms is either a very noisy radio environment or defective hardware. It’s freakishly outside of normal for the technology - if you were seeing 5ms, maybe 10ms, that’d be within expectations but not even 50ms.

      Clearly even modern devices are nowhere near 5ms but hey, let's just agree your perception is more forgiving.

        Modern devices should be in the 10-15ms range. If yours are not, return them as defective. The 5ms I referred to was the difference versus a cable - I’d expect a modern keyboard to be under 10ms and Bluetooth to be under 15ms. Since I’ve measured that the latency for a keystroke to render on screen in VSC at 16-24ms, I’m comfortable saying at least Apple has Bluetooth latency under that level.
