A lot of folks reading sensationalist articles about the PC market decline are making the conclusion that nobody likes or uses PC's anymore since sales are declining. The author is pointing out that it's a poor conclusion to make since there are other factors contributing to the decline, including the fact that the usable lifespan of today's PC's is longer than it used to be.
And that's a huge difference for the application developers so it's not only about being smart, that's a very relevant question.
