OK, first of all the Fuji Team as a full carbon frame while the trek is aluminum with a carbon fork.
The 2010 Fuji Team comes with full Ultegra, the next step up from 105, which you find on the Trek. And the Team has a list price of $4000. Did you mean the Fuji Roubaix 2.0, which has Tiagra? Fuji doesn't sell a full carbon bike with anything less than 105. The Roubaix also has an aluminum frame with a carbon fork (the Roubaix RC upped that with a carbon rear).
The Fuji Team is a far superior bike in every way (lighter, better components). Right now, Performance is dumping 2009's, selling 2009 Teams for $2k, half price. I bought my son a 2009 Roubaix RC with Full Ultegra for about $1,150.
If you were going to spend $1,700 for the Trek, find a little more and get last year's Fuji Team. If you can't, spend a little less and get the RC, it's still a better frame and better components. You'd have to go up to a Madone 5.2 at $3,150 to find a similar quality Trek to the Fuji.
