As it can be understood from the Iphone example, the strategy that Apple is using consists keeping the highest initial price that the first customers will pay and as soon as the demand of the first customers is satisfied (commonly known as innovators group), the company will lower down the prices over time. But if we were to think in matter of perspective, then you wouldn’t buy an IPhone 4 now because it will be inferior to the current Iphone. This can be one big disadvantage of the skimming pricing strategy, as the companies can develop negative publicity if they lower the price too fast and without significant product changes.
