Yeah, I’ve got a logitech mouse but didn’t want logitech’s software on my machine, so I just used the mouse by plugging it in. Which worked, but I had no way of knowing the battery level until the mouse itself started blinking low power.

When I installed fedora, I was confused a bit because it had a system tray icon saying the battery was charging. I was thinking it thought it was a laptop until I realize it had just picked up the battery information from my mouse. A feature I had written off under windows just worked without me even considering it or needing to install software that was partly about using my hardware and partially about advertising more ways to get my money.
