The new Samsung Galaxy S8 has launched, and its target of choice is the as yet unlaunched Apple iPhone 8 Anniversary Edition. These phones are critical for both companies. Apple survives largely off the iPhone today, and Samsung is trying to recover both from its burning phone problem and from its top executive being arrested on bribery charges. Neither firm can afford a big loss to the other, and Samsung just came out of the gate with one hell of an opening salvo. Apple can focus on product, though, while Samsung has to restore its image.
