I read an interesting blog posting by Ben Thompson who basically says it's silly to think all Ive is doing is updating the visual aesthetic; that the changes are only skin deep. He provides a quote from Ive from a few years ago: To me, "human interface" means not just how something looks but how a user interacts with it. From what I've read the HIG group is very small, similar to the industrial design group. And like the ID group the HIG group is locked down and only certain employees are allowed in their lab. Here's a recent job posting for the HIG group. Actually sounds quite interesting. https://jobs.apple.com/us/search?#specs&t=1&so=&j=DES&lo=0*USA&pN=2&openJobId=26917597 I think the media is getting too hung up on the whole flat vs skeuomorphism and thus is creating this meme that all Ive is doing is re-skinning iOS. Now it may be that we see more visual changes in iOS 7 because those were easier to implement in the time they had, but to assume all Ive is doing is getting rid of faux leather in the calendar app is a mistake, IMO.
