Vlad Savov, The Verge:
Until today, it was believed that only Apple could get away with mildly refreshing its flagship smartphone device without suffering an apposite dip in sales and consumer interest. Now, Samsung is emulating the Cupertino strategy in a bid to prove that it is every bit the globe-conquering big timer that Apple is. The Galaxy S4 design is, quite literally, the Galaxy S III’s design expanded to a 5-inch screen size. It moves Samsung further away from Apple in terms of pure specs and measurements, but it closes the distance between the two mobile leaders in terms of strategy.
“But if it looks the same, how will people know I upgraded?”
