Users don't "want" gigantic bliddy phones. Marketers give extravagant presentations to justify their positions, claiming that users want big phones. Then the engineering team is instructed to design big phones. Then only big phones are available. If it doesn't fit in your pocket, at least make it comfortable to hold in your lap. Now marketing has "data" that appears to indicate that people want even bigger phones. Repeat, until the form factor beggars the moon.
