> I've just never encountered the level of non-technical user that would be lost but for those particular touches. They say that economics happens at the margins. In other words, changing the price of a sandwich from $3.40 to $3.25 isn't going to make you buy 10% more of them. But in the population of consumers, there is a chunk that are on the margin that will be totally converted, and that results in a 10% volume increase in aggregate. Something similar may be going on here. Make a design tradeoff (using leather) in order to get a 10% user benefit, even if 50% of your users get no benefit.
