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 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.
