Though Apple designer Jonathan Ive was largely responsible for the iPod's overall look, it was Jobs who pushed for increasingly simplified designs and fewer buttons.
The most notable but maybe the most overlooked feature was the lack of a dedicated on-off button. Turning it on was as simple as tapping any button; to turn it off, users held the "Play/Pause" button for two seconds. (The iPod also automatically turned off after minutes of inactivity.) Some users were mystified by the "omission," so much so that some user forms were populated with questions like, "How do I turn it off?"
Now, it's just another "feature" we take for granted.
