Monthly cell phone minutes

I suppose this may not be strictly related to lopomo, but according to IT Facts.biz, the average American cell phone subscriber spends 619 minutes per month on the cell phone:

According to Telecom Regulatory Authority of India, Indian subscribers are the fifth heaviest phone users at 309 minutes per month per subscriber. While subscribers in the US talk the most at 619 minutes a month, those staying in Canada are the second highest users with an average usage of 344 minutes a month. Telephone usage in India ranks higher than the fastest growing telecom market in the world - China, where subscribers talk an average of 261 minutes a month. According to the survey, conducted by Merryl Lynch in September 2004 across 40 major telecom markets, the average usage is about 235 minutes per month per subscriber.

That's about 20 minutes per day ... seems plausible. Actual talk time is probably responsible for relatively little of the overall energy use of a handset & charger, but it's a fun statistic nonetheless.
