Nah, his points go like this:

- There is a pretty sizable Linux userbase compared to OS X. Not larger, but the same league.

- Any existing Windows PC can be installed with Linux, and many other non-desktop devices already run Linux, so the potential for growth in userbase given the right trigger (i.e. games) is much larger

- A significant portion of machines that run OS X have very low performance hardware. The Macbook is one of Apple's top-selling computers, and it has always lagged in graphics.

So, to wrap it up, both Linux and OS X currently have small share, but Linux has the potential for rapid marketshare growth on capable hardware, while OS X has neither.
