For me it’s the paranoia surrounding webcams. People outright refuse to own one and I understand, until they go on and on about how they’re being spied. Here’s the secret - unplug the damn thing when you think you won’t use it or haven’t used it in a while.
They, whoever it is, can’t really spy on you on something that’s already off and unplugged!
I agree with everything except a wireless mouse. I have a magnetic usb “nub” that plugs into the mouse so when I need to charge it every couple of weeks it’s as simple as moving the mouse near enough the magnetic cable and it pops into place.
For me, the benefits of a wireless mouse far outweigh the imperceptible-to-me lag from the 2.4ghz dongle 10cm away in clear view. The only downside I can see is the weight of the battery, but I’m not a competitive FPS player so I’m good.
I like wireless for my laptop, but I’ve never understood the point on my desktop. It’s never going beyond the cable’s length, and the cable has never gotten in the way unless I’m doing extreme motions with a very low sensitivity. And in that case, I am playing competitive fps.
I just hate the dragging of the wire on anything that might be in the way. I go wireless for keyboard and mouse whenever possible.
