“The huge success of the Apple 4S, especially its Siri voice interface, has brought about the first big choice of Tim Cook’s reign as Apple (AAPL) CEO,” Dana Blankenhorn writes for Seeking Alpha.

“It seems Siri means 4S users consume twice the data each month as other iPhone users, based on data from Arieso, a British market research firm with offices in Atlanta,” Blankenhorn writes. “As a result, there’s a growing divide between “data hogs” and the rest of the data universe, with 1% of users consuming half of all traffic, and 10% consuming 90% of traffic.”

Blankenhorn writes, “Why does this matter to Tim Cook? Because all the big telcos, not just AT&T but Verizon even Sprint, are now limiting downloads from these heavy users, while they fight to catch up. As the number of Siri users grows, the pressure will mount, and the latest estimates are Apple will sell 125 [million] iPhones this year alone.”

“What’s needed, as Muni Wireless’ Paul Kapustka says, is someone who will build a network as powerful as the devices coming onto it, with simple pricing plans that encourage abundant use, rather than discourage it,” Blankenhorn writes. “That’s now Cook’s challenge. The question is, will he take it on?”
