Actually it's Gentoo based, not OpenSUSE.

I'm well aware of that. Chrome OS doesn't run the typical Linux stack though. No X11 (I think...), no GNOME, KDE, or other common desktop environment, no native applications, etc.

It does use X11, but ChromeOS uses its own WM (chromewm). If you check out the sources for ChromiumOS, you can see what all it uses, although there are parts that Google add on top.

There are ways to run native apps on it, but they are definitely tucked away for normal users/uses.

I believe he is referencing the ease of use for chromeOS rather than its connection to linux.
