Nothing against carbon, just be cautious of believing that the minute you get a carbon bike that you will be fast automatically.
That being said, when I bought my steel Jams Coda Comp with 700x28 tires bike for commuting in 2003 to replace my 1986 steel Specialized Stumpjumper with knobby 26x1.5 tires, yeah, I cut 10 minutes off my 10-mile commute the first day I rode it. But that's a pretty extreme upgrade, and mostly had to do with the wheels, I suspect.
I do get a kick out of people who are sooooo concerned with having the lightest bike, the lightest components, even the lightest shoes...when really just losing 5-10-15 pounds, whatever, will make them much faster than a lower spoke count.
Ride lots of bikes and then make your decision.
