Its bandwidth efficiency, latency, and jitter, actually. Just like in the old days of 9600 baud leased lines it was hard to get acceptable console performance, and now people have megabit connections and CLI performance is not unusually constrained over the megabit connections. Of course its only using a fraction of 1% of the capacity. Also remember that end users might have megs of bandwidth to carry K of voice traffic, but somewhere along the line there's someone constrained. Just like work offices don't have to be dumps, but its hard to put a beancounter $ value on not working in a dump, leads to a lot of open office foolishness.
