Cook was asked if this is what Jonathan Ive has been working on.
He replied: "Yes. What we did last fall was change things up — to really ramp up our innovation. The key in the post-PC era for having a great product is incredible hardware, incredible software, and incredible services, and to combine them so you can't tell what's what. The magic is at the intersection."
"So what we did was amp it up. We recognized that Jony had contributed significantly to the look and feel of Apple over many many years, and he could do that for our software as well.
Cook didn't want to comment when asked about former SVP of iOS Software at Apple.
"I don't want to talk about people who aren't there. The whole concept is to tighten the groups even more, so we could spend more time finding magic at the intersection. Now it's seven months later, and I think it's been an incredible change. Craig is running iOS and OS X, which has been fantastic. Eddy is focused on services. It's been great."
Apple is set to deliver is WWDC 2013 keynote address on June 10th. The new iOS is said to be 'black, white, and flat all over'.
