The router side could turn the argument.  "With a routed backbone, you can
actually SEE what is happening to your packets.  It is not a hidden unknown,
thus prone to failure you can not diagnose.  With routers you know it went
bad at nqu1.  With switches, it just went bad."

Cynics mike argue that lack of end user visibility of network problems
is a compelling argument *for* NSPs to deploy switched backbones ...

("No, our backbone is just fine, { the NAP lost your packet | it got
  stolen by the packet fairies } " etc ...)
