3750s can do wonderful things for not only stacking, but redundancy and
load-sharing.

Traditionally if you have redundant links, you connect servers to
different switches, and each switch has its own uplinks to the core. 
Spanning tree will block "one" of them.

With 3750 stacks, you run cross-stack etherchannel.  You don't pay the
STP blocking penalty.
