I've always stated that "switch" is a marketing term meaning "fast". Thus a "L2 switch" is a "fast bridge" and a "L3 switch" is a "fast router". In this light, the Yankee Group is just now catching on to something we all knew a decade ago -- slow (i.e. software) routers are dead. There's a more interesting level to the discussion if you look at what carriers are interested in for their backbone hardware today; while I'm obviously biased based on my employer, I've seen a lot more emphasis on $20k-per-10GE-port "L3 switches" than $200k-per-10GE-port "core routers" in the current economic climate.
