This is not even close to the worst ideas Apple ever had, even if you're only talking about mice.

The original USB mouse (for the first iMac) was round, so you couldn't orient it in your hand without looking at it constantly.

And it came with a very short cord (because there was a port on the right side of the keyboard to plug it into). But then the laptops got updated with USB ports and they were only on the LEFT side of the case.

For at least a year or two you could not buy an Apple mouse for your Apple PowerBook and use it in your right hand, because the cord was too short to go around the case.

Eventually they shipped a "Pro" mouse with revolutionary elongated shape and longer cord. (...and optical tracking, and what looked like zero buttons, which were pretty neat)
