To be fair, this discussion isn't about that link. It's about Gruber's post, which is almost content-free. When you start a discussion with a link to a blog linking to a blog, you need to be prepared for things to get a little far afield.

And I'll admit: I'm detecting (both in Gruber's post and in the discussion here) an awful lot of simple anger at Isaacson coming out as needless nitpicking (c.f "He mispelled OS X!" above. Seriously?).
