I will say, Apple has always tried to pride themselves in aesthetics with design with the Mac/Apple Watch/iPhone, etc. So I do know the design is very important to them, which they would want to be important to the customer buying their product, because they want it to ‘stand out’. I just think in general when it comes to smart phones, I really don’t care about what it looks like, as I just need it to execute the task that I expect it to.
Most people these days use a case to show style anyway.
