Seriously, what is the point of these things? What problem do they solve and is it worth the extra maintenance hassles for non-racing riders?

You can run lower pressures without the chance of a pinchflat, there is nothing to pinch. This can be usefull off road when you want lower pressure for traction. Otherwise they don't solve any problem IMHO. Personally I can't be bothered with the hassle.
