IMHO, you won't go wrong with a cyclocross bike for commuting. The wider tires allow lower pressures that smooths out cracks and ruts in the pavement. It also allows for fitting even wider winter tires or tires with studs. Since you could fit wider tires and full wrap fenders on your Milano I agree with the others that it already is a perfect commuter... just needs lights.

Here is the commuter I use based off a Canondale CADDX (54 km roundtrip 3 times a week).
