I commute on a 2008 Schwinn Fastback. Did the commute on my roomates mtn bike for 3 weeks before purchase to make sure I really wanted to do it. Love commuting on a road bike because it is much more intense and demands more focus than something with wider tires. Commute is only 4 miles each way and I can get to work in 15 min. in the morning. Extra speed = extra time in bed for me.
