Good comparison of how Apple is more diversified than Microsoft, Google, or Adobe. From Ron McElfresh in Mac360:
Apple focuses far more attention on the user experience than Microsoft, Google, or Adobe. After many years of toiling near death and obscurity, that relentless attention and focus has paid huge dividends for Apple; unrivaled by their competition. Unlike the other three, Apple doesn’t throw product ideas up against the public wall to see what sticks.
Or, “It’s the user experience, stupid.”
