Picking up the discussion of vendor share, I used Canalys estimates of platform shares to visualize the effect of Android on the smartphone market:
The best way to get to the essence of any company is by evaluating its priorities. These priorities are like an unwritten constitution. The analog in theology is dogma which when codified becomes doctrine. In law it’s common or case law. In business, priorities are hard to discern and are usually only anecdotally observed.
At Apple the top priority is the product.
Sounds trivial, but very few companies place product first. Those who do tend to be producing creative works (e.g. movie or advertising studios, companies built around a creative process). Most companies place either production or distribution first.
Placing product first forces the bizarre behavior that Apple is well known for: being innovative and quixotic. It makes them foolish and hungry. Sometimes it even makes them catastrophically destructive to competitors.
