All the numbers and percentages I used came from Apple’s financial statements. Mac sales have gone up significantly since 2009, but the NPD survey you quoted is in line with what I wrote earlier. As for Mac Pros: of course that market is tiny. There are no official sales figures available, but I estimate that around 2 million Mac Pros were sold in the US in the last 4 years. That’s less than 1 percent of the population, but a lot more than 1 percent of 1 percent.
