You'll likely hear crickets on that. Or some hand-waving obfuscation about how design is structured at Apple (despite having zero demonstrable inside knowledge).
It's kind of like the hackneyed and tired (and apparently crowd-pleasing) whine "Apple doesn't innovate anymore." Yet when asked for a handful of innovation suggestions it's crickets again. Or maybe something lame, and hardly innovative, like simply porting MacOS to iPad, which Apple considered and rejected long ago.
In the end it's Apple's roughly 1 Billion active customers, many repeat, that speaks to Apple's massive success and with that, the ability to innovate (causing customers to keep purchasing Apple products - year after year after year). That massive success apparently irritates some people - which is pretty silly. And also speaks volumes.
Quite a lot of straw men there.
As to innovation? Let’s take one example: Apple Home. Apple is in a position to revolutionize the smart home. It’s a classic example of the kind of market Apple targets. Lots of companies making lots of devices that maybe work together and maybe don’t accompanied by a load of different applications to control them that have inconsistent and often user hostile interfaces.
The range of smart home devices that Apple could be developing is wide and deep. The demise of the AirPort basically signals that they have zero interest in it though.
And Home is only one of MANY areas Apple could be innovating. Look for another example at the market for high end audiophile players. Astell & Kern, Luxury and Precision, Cayin and a dozen others are doing really interesting things with what basically amounts to a modern day iPod. These devices blow the iPhone away many key respects.
So let’s not pretend that Apple’s success for their share holders equates to success for their users. Raking in billions of dollars speaks more to their marketing than it does to their leadership in the innovation space.
