Neil Hughes of AppleInsider reports "Galaxy S III passes Apple's iPhone 4S, becomes top selling US smartphone." The real reason Apple sued Samsung is that is could not stand the thought of losing its once-held monopoly on full-screen smartphones. That's the "value" Timothy D. Cook is talking about.
(Only in the USA does the iPhone still dominate; places like Spain show Android having a 90% market share of smartphones. My daughter-in-law last week chose the S III as her replacement phone. It's a lot sexier looking than the rather bland 4S.)
As for those predicting that Apple will next sue Google, they are those who have never used Android after version 2.x. Google made sure that its operating system and that its Google-branded phones look'n feel nothing like iOS or iPhones. Trust me, iPhone users: you'll be lost trying to navigate an Android v4.x phone. It's just that different.
As for Mr Cook's claim that Apple is primarily interested in innovation, that would be an inadequate explanation for why Apple now copies features from Android, such as notifications and larger screen sizes. With versions 3 and 4, Google moved Android so far ahead of iOS so quickly that the now-seemingly-laggard Apple is scrabbling to keep up to the competition.
iPhone users tell me the 4S disappointed them with its lack of significant improvements and by the lackluster Siri performance. They're starting to no longer believe any old Apple exec's claim that it's "great." This month's upcoming release of iPhone 5 better not be a repeat, for Apple's sake.
