I was surprised to see this thread pop up again, but anyway I eventually bought the Townie last spring. I bought the Townie 8 which comes with the internal hub and fenders. My commute is 10 miles, small rolling hills. I have two other bikes so I don't ride it everyday.
The good:
-The bike is very comfortable for less than 10 miles
-I can wear any type of clothes, or shoes.
- Perfect utility bike with a rack (unless your carrying so much that you need a front rack too)

The not so good. (Depending on how you look at it)
-It is a slower ride (Im not out to win any races anyway)
-Not as agile as other bikes. I wouldn't consider jumping curbs and all, but with fat tires theres no need.

When I first got the bike I had problems with the rear fender. The screw came out and it was trapped in between the tire and fender. A little loctite solved the problem. I still ride my trek 7.2fx the most, but thats partly because it has the lights on it. Also most of the time I do like to go somewhat faster than what I can do on the townie. My farthest ride on the townie has been about 20 miles, and at that point the seat was not so comfortable anymore, but it does not chaff me. All in all its a good bike for those quick trips to the store, or places wear I want to wear regular clothes and not have to change.

Just another note, I have a puegeot with clipless pedals, but i only ride it for recreation or to commute because when i go to the store, i dont like walking in cleats, and i dont want to bring a change of shoes.
