Ben Thompson, "The General Purpose iPad and the Specialist Mac":
Ultimately, it is the iPad that is in fact general purpose. It does lots of things in an approachable way, albeit not as well as something that is built specifically for the task at hand. The Mac or PC, on the other hand, is a specialized device, best compared to the grand piano in the living room:2 unrivaled in the hands of a master, and increasingly ignored by everyone else. Great metaphor. See also: Federico Viticci's thoughts on the iPad's --- and, more importantly, iOS's --- future.
