Given the recent surge of mobile phone and device use, we’re surprised that this has yet to happen, but it looks like 2007 might mark the first year during which the average U.S. household will end up spending more money on cellular service than landlines. As you can well imagine, landline use has been declining for quite some time, with many families and individuals getting rid of their landline service entirely in favor of a mobile solution. In 2006 consumers spent an average of $524 on their cell service, compared with an average of $542 on their landlines. When the chips fall at the end of ’07, however, the numbers are expected to have shifted in favor of the cellular industry. Nice work, guys!
