Android's Product Rollover Dilemma

(12/4/2012) I found this is a very article to talk about product improvement and model generation rollover problem in new product innovation. Except the maker of Galaxy -- Samsung, other makers of Android smartphones cannot launch a product that can really compete with Apple's iPhone neck to neck. The strategy of these makers is to launch a lot of Android phones more frequently. (In Taiwan, we use a term "機海戰術", indicating the makers just make a lot of models.) This is partially due to lack of negotiation power with wireless service provider, hence the makers need to differentiate their own product with more models for various carriers. (Apple has one model for all carriers.) For android's users, it triggers more frequent and quicker "buyer's regret" because their new phone will be 'dated' in several months. (Apple renews their iPhone roughly every year.) Another bad impact for Android makers is they will need to provide more software updates for their various models with various versions of Android OS. Do you see the headache of Android makers?
