vitaminwater is the subject of the latest Slate “Ad Report Card” column. I have liked the stuff since I first saw it on 10/$10 sale. My favorite flavors are the red ones, the new XXX and Power-C. A friend alleges that all vitaminwater causes digestive … unpleasantness. Fortunately, I haven't had his problem. Also, the euro talk show ad is great – far better than any attempt I’ve seen for example on SNL since Sprockets.
