We have a humble core of year round commuters at our company. I choose from my several bikes for my commute, and I never miss a day, but a few of the guys/gals have some nimble looking CX bikes that look really nice. One guy has a Specialized CX that looks pretty nice, and another guy has a Salsa. A woman from work is having a carbon fiber Calfee made for her for winter commuting. Seems extravagant, but maybe not so much if you're a committed commuter. I kind of lust after a german made Tout Terrain for the ultimate commuter.
