After reading this article, it is unclear to me what "The Myth of the Thinkpad" is. The author laid out a series of desirable attributes about Thinkpads, and proceeds to explain how they are all true. We are reminded that all these desirable qualities arise from business realities, which is generally true for any desirable attribute in a commercially successful product. In the end, there's a conclusion that Thinkpads are a good choice, but that they are not "magic", as if this was something that needed explanation.
To put it bluntly, the author thinks that people who praise Thinkpads are dumb. They think we all believe that Lenovo/IBM listened to us lowly nerds and forged a one of a kind Thinkpad to satisfy our dream of a serviceable and durable machine, and not purely to make money.
