Had a pleasant weekend of making things and maintaining equipment. One of the things I did was fill the bottom of my mechanical keyboard's case with silicone for additional thonk. This meant losing the battery and going back to USB instead of Bluetooth.
Wow. I wasn't aware how much that tiny latency (BT) was making my computer less pleasant to use. I've gone back to a wired mouse, too. There's a lot of things that contribute to modern comps feeling slow, but this seems like one of them, for me.
