I've looked at them for commuting. There are a few around and ridden by what appear to be very stylish people. However, I have to do some hills on the way home and the bikes just look too heavy and slow with none or few gears.
I guess if your trip is fairly flat and you're not a speed demon, then it'd make a sturdy basic bike with very few mechanical things to go wrong...
Let us know if you get one.
Cheers!
