How about another incomplete reply to your question?
I ride a cyclocross bike as my main commuter now, a Specialized TriCross Comp. It's aluminum with carbon stays and fork. My other commuter is a hybrid style, not a touring bike, so I can't speak to the comparison. The cross bike is much faster than the hybrid, that's for sure. In my opinion, cross bikes are where it's at for commuting.
When I was shopping for my new bike, I looked at the Felt and I thought it looked really good. LBS said they hadn't sold many yet so couldn't tell me much long term about it. Of course lots of folks like the Surly.
