Pros look at bikes as tools of the trade, where as I expect many of us develop an affinity for our bikes that goes beyond that.
That said, I'm honestly pretty disgusted with bike prices already. The idea of paying full price for Specialized is comical - everyone I know who rides a Spec gets some sort of bro deal, team discount, or whatever. I recently saw a Cervelo S5 "special" edition for like $7500 for the frameset. Just nuts.
But hey, for people in the masters' field who want to rock a $15,000 bike in the local crit, more power to them. If you can afford it, and it makes you happy, there are a lot worse ways to spend that $$.
PS. That Colnago's not as ugly in WC colors, but I guess that's what "lipstick on a pig" means.
