Hi, Great Article Wendell.. :)

Cisco's/ CiscoPress Literature, Blogs & Documentaions on IT Networking Technologies are the best in depth and quality content. It has a huge Cult Following and is The De facto Standard for anyone entering into the IT Networking Domain or the TCP/IP space. Even Corporate traniers for various IT Networking, Network Programming and Product Support Companies recommend CiscoPress books to gain insight and knowledge on Computer Networks. Afterwhich, they will concentrate on their respective Product Tech training.

Thus, every Network Engineer I have known for the past many years in some way or another will be loyal & inclined to Cisco Systems and it's IT Networking Technology adavancements/ achievements, plus they will find the Competitors networking technologies incomplete, inferior and lack of feature set when compared to that of Cisco.

Hence, this will automatically built trust and respect for Cisco Systems Inc. which other companies lack alot (Recently, #EMC #VMware realized the same & is trying to enter IT Networking market by pushing forward it's own IT Cert for SDN NSX to gain faith and trust for it's technologies from the existing pool of Network Engineers who are currently knowledgeable in Cisco Products and Tech http://searchsdn.techtarget.com/news/2240228172/VMware-calls-future-NSX-certifications-the-next-gen-CCIE).

But Competitors currently don't have a huge fan base when compared to that of Cisco's. This is Cisco's most powerful Advantage. I strongly believe this is the major selling point for Cisco as Enterprise/ Business CIOs/ CTOs, Enterprise IT shops, IT technocrats educated with Cisco Tech/ Products will trust cisco products for their innovations, efficency, reliabilty, stability and scalability. Which will promote them into Decision making tending towards choosing Cisco Products and Buying Cisco Equipments for their TCP/IP requirements to fuel Enterprise growth in the current information age.
