Unfortunately the article author and at least one of the commenters - "ACF" lack pertinent knowledge about *BSD based UNIX-like operating systems to allow article credibility.
There are "at least" two (2) FreeBSD based Desktop distributions - PCBSD and GhostBSD that provide a complete Graphical Desktop experience with easy installer, which is in my opinion just as uncomplicated as any GNU/Linux distro. Even the new Sony Playstation 4 employs FreeBSD for it's Graphical Game console.
In regard to Servers, Juniper Networks, Yahoo, Sony and Fujitsu amoung hundreds of corporations, and the DOD and other USA government departments and agencies rely on BSD Servers. Recently Netflix chose FreeBSD (over Windows and Linux) for their Network Server Appliances, installed in national Telcos facilities, for more efficiently and reliably streaming millions of movies to customers each week. Verisign chose FreeBSD as equal requirement OS to Linux for their Certificate Authorization Services worldwide.
This very robust and complete OS is also very popular and Server OS of choice for many large USA and International Technology and general education Universities, as well as for Scientific and Engineering research centers.
It is critical that those commenting on technology issues become more informed before making incomplete and/or stupid statements.
