I ride my only bike to work. While not overly racey, its far from commuter. But I still have a seat bag/pump/etc for when i get a flat. I commute with backpack, jersey/bibs, and have a good time hauling to/from work.
I will say though I'm humbled at the people that commute on commuters and other bikes with smaller chain rings. the last .6 mi of my commute is nearly 8% (ugh).
