So you stopped reading an article because the guy does not use your preferred operating system then justify your bias from comments that (at the time of your posting at least) have no evidence that the article is "lame".

Well done.

There is a lot of oldschool guys who are very professional developers in their fields, but who are reluctant to change their OS. I don't think the latter is good or wise, but they are still very knowledgeable in their field. E.g. it's not uncommon to see an embedded Linux developer who uses Windows as his desktop OS.
