i guess some people are too young to remember wired mouses
I only use wired. Batteries and charging suck.
Wireless has gotten pretty good over the past few years. I have a super cheap wireless mouse from Aliexpress that I use to control my PC while I’m on my couch (I have the PC plugged into my TV to watch Youtube videos and play the occasional game) and I only have to charge that thing every 2 months or so for like 20mins. The much bigger problem is the annoying latency and random connection breaks, but that might just be a factor of the mouse being super cheap.
My keyboard does both wired and 2.4ghz wireless with a physical toggle and it’s super reliable, but I have no idea how long the battery would last because I use it wired for my work Laptop during the day and wireless on my couch at night, so it’s basically always at full charge.
I use one on my main computer. It still works while charging, and even on Linux I get a notification when the battery goes under 10%. I plug it and use as a wired mouse for the day, and maybe leave it charging overnight and unplug it in the morning. Had it for 8 years now, never an issue.
