Jokes aside (of which I too have already posted), as a designer, I have no problem adding this resource to my library. Will be one of the gems of my collection. No matter the type of designer one might be, Apple has likely had an effect on - at the very least - the way we think about design (if not the outcome). The idea that thoughtfully determining the best user experience will inform the required design is an approach that can be applied to many situations - even outside of more formal design challenges. Designing, parenting, governing... You will never fail if improving the end user's experience is your driving focus.
Very true. Working in marketing (in a very different industry than Apple) we still use Apple as a benchmark if we can during specific situations such as branding, aesthetic design etc. For some of us Apple is about more than a Phone or a computer. The ideas and design principals are the very reason MOST of the design team has worked at Apple for 20 + years. Not many other people (especially younger) can say they've been or plan on staying at the same job for up to 20 years.
