Provided with the condition that bikes can be brought into the workplace, theft would be less of a problem.
Is road-cycle-commuting recommended?
Yes, I recommend it. I love commuting on my road bike. Fast, fast, fast. No racks and panniers either, I just use a backpack. Nothing that isn't required by law gets attached to my road bike.
However, when you say, "instead of," I would say "in addition to." I also have a foul-weather bike with full fenders for those wet days when the road bike isn't the best option.
But yes, if your goal is to burn up asphalt, get a road bike. Anything else like a cross bike or touring bike, you'll probably regret it, wondering what you're missing out on. Avoid getting a cushy seat though. Stick with a good road-bike worthy saddle. Search the Road Biking forum for saddles, and you'll get tons of recommendations.
