How often would you leave a $2k road bike chained up outside, without a line of sight to it? Me: never. You know, I never ever see a high performance bicycle locked up. Any S&S bike is going to have a frame worth nearly $1000, since the retrofit costs minimum $400.

I think that's the biggest hassle with an S&S. It feels great, it rides perfect. No difference from a normal bike. But I can never feel comfortable leaving it out alone, which is one frustration I don't want to have sometimes while traveling.
