Another contender might be a Specialized Sirrus Pro

It uses several of the same components: Shimano 105 group, Avid brakes, FSA Gossamer triple crank, a carbon fork, etc. A bit wider tires at 700x28 and comes with a 4-position stem.

Either the Kona or the Specialized would make for one mean, fast "casual rider" that might blow some minds with its upright riding position, wide seat, and swept back handlebars.
