The New Yorker profile of Jony Ive:

Later that day, I asked Ive about an Apple design that shares the new campus’s formal simplicity: the circular “hockey puck” mouse that was included with the first iMacs. Many found it hard to control, and it is widely considered a design failure. Ive didn’t accept that description. He referred to different schools of thought about arms, wrists, and mice. “Everything we make I could describe as being partially wrong, because it’s not perfect,” he said, and he described the wave of public complaint that accompanies every release. He went on, “We get to do it again. That’s one of the things Steve and I used to talk about: ‘Isn’t this fantastic? Everything we aren’t happy about, with this, we can try and fix.’ ”
