No Campy on my bikes but then again the only Shimano is a front brake caliper and a fixed cog on one bike. There's no reason not to use Campy on a commuter other than Campy stuff tends to be expensive. Shimano or SRAM MTB components tend to be sealed for better longevity in adverse conditions and are usually cheaper which decreases replacement cost. But if you like Campy and don't mind spending the money then go for it. For myself my commuter will continue to run the cheap low maintence fixie stuff.
