Article is in Wall Street Journal so unfortunately you need to be a subscriber to view it, but it discusses the high cost of maintaining a chlorine pool, the problems with the smell of chlorine, the irritated eyes, faded swimsuits, etc. and how SWGs are a great alternative. My favorite quote: "Traditional liquid and tablet chlorine costs up to $700 a year for a residential pool owner. Periodic so-called shock treatments to raise the chlorine level can be $150 and higher for a home pool, depending on pool size and use."

I posted a link to TFP in the comments (which, by the way, can be read for free - very entertaining to see how many problem people have with their pool maintenance and how SwimSpray is a favored solution).
