For sake of correctness — recent versions of Phantom.js are not dependent on Xvfb or any other variant of X, and there are grandmotherly prepared binary builds on the official website (kinda statically linked, so no dependency on WebKit as well). Not that it changes the author's arguments that much, but just worth pointing out.
