AT&T Wireless boss Ralph de la Vega is still telling the press they misinterpreted his comments about possibly pushing iPhone users toward a consumption billing model. A few weeks ago, de la Vega insisted the company needed to find "a pricing scheme that addresses the usage." Given the comment, investor pressure to ditch unlimited pricing, and AT&T's history of insisting that usage-based models are about being fair to grandmothers and preventing the end of the world, it was fairly clear to everyone where AT&T would like to go with pricing. Still though, de la Vega continues to insist he was misunderstood, telling Business Week he was simply talking about ways to get people to use less bandwidth:Actually, the most obvious solution continues to be to beef up the network so it performs like AT&T and Apple commercials promised it would. Demand is only going to grow, and if you're going to pitch yourself as the broadband company of the future, whining about people actually using your product isn't a solid foundation. Business Week again addresses the gap in AT&T network investment spending in contrast to revenues, and estimates that at this pace, AT&T's network won't be up to snuff until....2011 "at the earliest":Meanwhile, good old Sanford Bernstein analyst and lazy journalist quote machine Craig Moffett makes an appearance in the Business Week article. Moffett, who traditionally argues that network upgrades are stupid (because he'd prefer that money go into his and his clients' pockets) offers up this nugget of wisdom we'll leave you with this morning: "It's reasonable to think that heavy users are worth zero." Surely Moffett and his clients won't mind then when these customers, which he admits will soon become commonplace, flee to other carriers willing to spend more money upgrading the network.
