To be fair, the original author of the quoted article is probably doing most of the smoking of things. All Gruber did is restate it and add the obnoxious political snipe at the end.

Windows people, how much faster would a non-Windows machine have to be before you'd start to consider using something other than Windows? I know if the question were flipped and given to me as a Mac user, the answer would have to be something like "fast enough that the muscle memory and system knowledge I've gained from three decades of Mac use could be overcome by sheer system speed of the Windows machine," and that would have to be pretty damned fast. Given that it's pretty irrelevant to me to compare the two.
