real hardware router VS linux router

Not sure if this has already been mentioned, but what about solid state
hard drives?  Think they are in the high GB capacity now and solves the
problem of no moving parts?

Although I'm all for hardware based devices, we recently been to Cisco
to see the new Cisco ASR1000 switch uses an underlying Linux kernel :o

dislodged.
