I went from a Cannondale hybrid to a road bike last summer. The biggest thing was just getting used to how light it was, especially at high speeds. My road bike is 10+ lbs lighter than the heavy hybrid, and at first it felt like I might blow off the road!

The speed didn't take much getting used to; that was the best part about the switch. I still ride my hybrid when I take the kids in the Burley, and whenever I start riding it, I can feel the heaviness and slowness of the hybrid.
