I think it depends upon what your commute route is like. I don't ride to work much in the winter because the road is shaded (which means that it's usually icy) and there is no shoulder (not even a fog line) and the consequence of a mishap is a tumble down an embankment. Very ugly, not even counting the drivers!

Make note of where the shady spots, etc are and how you may be able to avoid them. Then go! You'll be glad you did, I'll bet.
