I was thinking more along the line of how am I going to carry all my crap to the train station. Having that option to carry a solid makes my life much easier. Public transport in Switzerland is so good you don't need a car, although it would be nice sometimes, until your stuck in traffic.
Man, the Internet sounds like a tuff place to ride.
