John Gruber offers his take on Apple's blockbuster last quarter:
The problem isn’t that Apple has changed. The problem is that Apple has not changed, and their continuing success is proving that conventional disruption theory does not apply to consumer-driven markets in which outstanding design and integration (as opposed to modularity) can drive demand.
Apple is disrupting the conventional tenets of business even more than they are any particular product category in consumer electronics. There is something fascinating — in several ways unprecedented — going on with Apple right now.
