Lot of opportunities for Apple yet seems as though Apple is being overly cautious in it approach. Time is important Yet actually perfecting a product or upgrade is more important. Hopefully Apple starts to give the customer more choice with 2 sizes of IPhones. However the real differentiator be their IOS and ecosystem
Google is way out of line with respect to users privacy. They have never protected customer info and privacy. They make their money by providing info. Google stores to much info about its users. Android is another system which returns Google money through info.
As with TV's , most cellphones will all look similar or identical to the iPhone in the future. The big differentiating factor will be the interface and software which the phones runs as well as the Ecosystem it has if any.
Of couse there will always be some new features with each cell phone released but they will not be the differentiating factor.
