I have two Bike Fridays - a Pocket Rocket set up as a road bike (ultegra components, skinny tires) and an Air Glide set up as a touring bike (mix of ultegra and XT components, brakes that can accommodate heavier tires). I am very happy with both bikes.
I ride my Pocket Rocket all of the time - it's my commuting bike plus my "just riding" bike. It has also traveled with me to places like Oregon, Hawaii, and Utah on trips where I wanted a bike but where I was not hauling my own gear with me. I rode my Air Glide across the US in 2002, and it has traveled to places like Ireland, Hawaii, and Prince Edward Island with me.
Leila Barker rode a New World Tourist across the US last summer. Her journal is at http://www.crazyguyonabike.com/journal/amphibious2005. She also participates in this forum, but I can't remember the name she uses here. You could leave a message for her in her journal guestbook though.
I'd be happy to try to answer specific questions - is there something in particular that concerns you?
Also - you may be able to test ride a bike, depending on where you are in the country and where there are New World Tourist owners. I believe that Bike Friday will still try to hook up prospective owners with folks in your area that have the same bike. That doesn't always work, but it's certainly worth a try.
