Quotes from the article:
"Amid all the ballyhoo and whoop-de-doo about Apple's resurgence being a result of the consecutive successes of the iPod and iPhone -- and the promise of the iPad -- one Cupertinian money-maker has been flying under the radar: Mac sales have tripled in the past five years"

"A glance at the just-finished quarter's SEC Form 8-K shows that the total Mac revenue of $4.4bn, though lagging behind the iPhone's $5.3bn, was still head and shoulders above the iPad's $2.2bn, iPod's $1.5bn, and iTunes' $1.2bn."

"In a conference call with analysts and reporters detailing the company's Q3 2010 results, Apple COO Tim Cook provided one insight into why Mac sales have tripled since Q3 2005: sales outside of the US, and especially in Asia, are skyrocketing on a percentage basis"

"Speaking about what he referred to as "extraordinary" sales-development prospects in Asia, Cook said: "If you look at the Mac as an example, in Asia-Pacific the Macs grew 73 per cent year-over-year. This is phenomenal, that we could grow by this much. And in China we grew 144 per cent. In Korea we grew 184 per cent. In Hong Kong we almost doubled."

"And perhaps more interestingly, the ASPs (average selling prices) of those Macs increased far more than their mere numbers: Apple pulled in more than $1.8bn in Mac sales from Asia-Pacific in Q3 2010, but only $703m in Q3 2009."
