Taken from the BBC Technology web site: The Japanese government is investigating a possible battery defect in the iPod Nano music player. There have been two reports of Nanos overheating in Tokyo, scorching nearby paper. Economy, Trade and Industry ministry official Hiroyuki Yo*****une was quoted by the Associated Press as saying the government is in touch with Apple to investigate the defect. A problem with the lithium-ion battery was suspected, the AP wire agency said. The report echoes an incident in March, in which the Japanese government stepped in to investigate an iPod Nano that overheated, shooting sparks. In 2006, Apple was forced to recall some 1.8 million lithium-ion Sony-made laptop batteries that were prone to overheating. Just saw this, thought it might be of some interest to some people on here. Not sure why to be honest. But it does look like it could be an issue.
