There is a lot of arguing, but really, nobody can convince anyone of anything on here. All I can say is that if it rolls and you can pedal it, it will get you there. It just might not be very fast or comfortable in the long run, and you will probably want to kill yourself the first time you encounter a significant headwind on your commute. But since you already have the bike, give it a try. I'm sure that if you continue to commute, you will eventually want something lighter - if not a road bike, then a good, fast hybrid, or a reasonably light unsuspended mountain bike.
