I'm confused by what you mean by "more portable." Do you mean that it runs on more CPU architectures and platforms? Or do you mean more driver support, etc.? BSD can run a rather diverse set of platforms: http://www.netbsd.org/ports/

Quantitatively speaking, Linux has a large share on diverse platforms, and is on the top usage as client (eg. Android), server, and embedded devices that run a typical computer OS.

I'm not confused, I assume they mean /more compatible/ (with hardware on the shelf).

All of these (expect for VAX) are supported by Linux too
