alt Hacker News> I think it was actually more related to aesthetic "icks" by the designers, because people would have disconnected the cable if it was in the way.
A lot of people really will just anxiously leave the cable in the whole time if given the opportunity. I have a wired/wireless Logitech mouse and I confess that I hardly ever remove the cable. Between this, and the space and connector issues of adding a "normal" cable connection as referred to in the grandparent, we have two reasons to think that Apple's decision wasn't all that clearly bad, let alone one of their worst.
Nobody leaves the cables attached. Except wanna be pro gamers who think a couple milliseconds will help them more than practice to "git gud". Every mouse I have is wireless, and I almost never use them plugged in, except for the one on the server that get used so rarely it's self-discharged should probably be wired but I simply don't have any wired ones left. Just plug them in overnight every once in a while, golden.
