He, we have used STP even for cabling the PBX (cat5.e) ;-)

In Europe is quite common (and also the SSTP variant) but on large 
companies (small businesses still use cat5 UTP and 10/100 devices). In 
fact, all of our patch panels use STP cabling and also the pigtails for 
conneting the computers to the swicth are also shielded. Yes, they are 
hard to work with but provide a much better resistance from external 
interferences and this was mainly the reason for us using it: gigabit 
cables share the same pipe with power lines, cctv camera cables (rg-59) 
and fire alarm system.

Agree.
