I was literally surprised to see that the web site is not responsive.
Neither is apple.com
Likewise on an iPhone
Why would you visit it on an iPhone?! I see the website as a developer resource, and I can't seem to think of a use case when you develop something/need to visit it on an iPhone.
There have been times when I've been on the move thinking about how to solve a problem, and would look up what libs can help me.
