I always though it's the other way around: less demanding places just 
buy a Cisco router (or whatever other big name solution), run it with 
pretty much default settings, as they don't have enough IT knowledge to 
run their own, custom solution.

But yes, it's a "religious" question.

On the other hand, nobody was ever fired for buying solutions from Big 
Vendor Inc., so I guess this is where your conservatives fit in, probably.
