OS X is technically correct, but it's 202M hits on Google for OS X vs 82M for OSX. As far as I'm concerned both are widely used by technical and non-technical people and mean the same thing. It's a tiny mistake that could be fixed in one second, why are we even mentioning it in the context of Isaacson allegedly blewing the biography?

A Google search is hardly the way to resolve that. OS X searches for anything with OS or X whereas OSX only searches for things with OSX so of course the former has more hits.

I mean you're right that it's technically "OS X", but your methodology for proof is flawed.

a search for:

os x

does what you say, but a search for

"os x"

does what the GP says, and matches with the numbers cited, too.
