Nokia is replicating similar products built on S60 platform at full speed. After releasing base model, another 3-4 products with small differences between each other in terms of functionality and design appear. Within a certain time interval the models don't have major hardware differences. A lot of things are just software changes, and few additional features, like different camera module, presence or lack of IrDA port. This method is great for saving money on developing new platforms, it's economically correct, but it also leads to problems with explaining differences between the models to the consumer..
