in addition to that:
In a datacenter that; where hundreds of servers (blade servers, usually web environment) are required, the 3548's (or 3550 smi),in a redundant (layer 2) and teaming nics for end nodes, these switches, with gigastacks, are usually within a few feet of each other and are great. The gigastacks offer more flexibility than fiber stacks. The gigastacks can stack to the switches and leave the other gig slot open for other uses (trunks or gig access ports whatever).
In our datacenters the gigastacks were alot more resilient (taking those unmentioned bumps from engineer running cables).
And scalability is a big reason.

Bob,
Price is probably a major reason. Last time I checked, the Gigastacks
are cheaper than SX gbics. Also, a lot of companies stick with 2900 and
3500s for closets. 4000s and up are considered distribution and core level
switches, with a price to match. Price per port is much cheaper for 2900s
and 3500s than a 4006 with sup 2 and line cards. Since most networks tend
to grow rather than shrink, upgradibility is also a factor. Once you've
maxed out a 4003 or 4006, you've got a big cost to add another chassis.
With stackables, it's much cheaper. Of course there are networks out there
that justify a 4000 or higher at the access layer, but those are special
circumstances.
