> moved on to big iron F5 and Cisco gear. Just pointing out that this is a perspective thing. PFsense and similar can very-much-so be just as "big iron" as Cisco et al.

Just making the case that "just buy Cisco" doesn't do anyone really any good in a very wide market with a lot of very good options - sometimes paying for the brand doesn't mean you are getting something better.
