I think we file this piece under unexpected consequences:

More pointedly, according to a study carried out by Jay Thaker, a 17-year-old high school student, which was presented to a selection of heart specialists yesterday, close proximity to an iPod can trigger monitoring malfunctions in cardiac pacemakers due to electromagnetic interference.

Thaker, lead author on the heart-related study and a student at Okemos High School in Okemos, Michigan, revealed that iPod units positioned a mere 2 inches from the chests of patients fitted with a pacemaker caused electrical interference in 50 percent of them. Even when located around 18 inches from a patient’s chest electrical interference was registered as disrupting the pacemaker’s telemetry equipment, leading the implanted device to misinterpret the pace of the heart. In one test the pacemaker ceased to function completely.

Perhaps we need a new subheading for unexpected consequences likely to lead to protracted legal actions.
