> 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.
