The Peter Principle in effect. Apple wants Ive to be the new Jobs but his software taste just isn't as refined and it's distracting from his hardware work which is getting lazy. The Apple Watch is literally an iPhone on your wrist[0]; it's quite ugly for a watch. I'd rather have Jony back focused on hardware instead of failing upwards.
