Why must everyone keep putting out one 48-port 10/100/1000 switch after 
another, while no one (other than D-Link and such) will put out a dense 
SFP version of the same thing?

Personally I'd like to see this in a 16-port GBIC version too, with the 
cat4k sup modern enough to do baby jumbos. 3550-12G doesn't cut it, 
neither does 4912G.
