I hate dishonest marketing as much as the next person but I don't think it's a stretch to say that there is nothing wrong with telling a good story about a product. And of course, telling that story means de-emphasizing unpleasant tradeoffs, and emphasizing pleasant ones. The ultimate concise version of this would be a list of features. That wouldn't be nearly as exciting or informative, would it? (I recognize that you did not personally advocate the position you relayed)
