It was certainly expensive, but I ride 12+ miles a day commuting to work so the benefits are worth the money. The carbon frame and slightly-wider tires dampen a lot of the vibration that you find riding on the road grid from pebbles and cracks. The handlebar is also a little bit raised so I'm not bent so far forward that I can't see the cars around me. And good lord is it light. I accelerate out of stoplights faster than most cars, and it makes climbing hills much nicer.
I made a map of some of the routes I use to get to and from work. Click here to have a look at it. One of these times I'll bring my camera along to get some views of the SF Peninsula hills. I get chills and shocks at how lucky I am to live here each time I go riding in them.
