100Mbps switches are getting cheaper.  The rest of the infrastructure, for a
large LAN, to support putting in 100Mb switches at the desktop without
oversubscribing building and campus backbones, adds up to sizeable sums very
quickly.  a 24-port 100Mbps switch needs a gigabit uplink -- those prices
are significantly higher.  Start counting to see when the gig uplink becomes
oversubscribed and insert more $$$.
