In my post about why the iPhone is minimalist, I mentioned that the Home button serves a single purpose: to return to the home screen.
I’d say this is true the majority of the time. However, Luke Wroblewski actually came up with thirteen different functions for the Home button, most of which I hadn’t thought about.
I stand corrected, but Luke’s list doesn’t make the Home button any less minimalist. After all, one button is far simpler than thirteen different ones.
