Apple just can't seem to catch a break when it comes to heat issues.  Its iPad overheats and dies on sunny days.  Its new MacBook Pros apparently at times get hot enough to boil water -- or your skin.  And of course the company has suffered from infamous reports of iPod Nanos and iPod Touches catching fire and exploding.

The latest incident comes from the island nation of Japan.  A Tokyo resident was listening to her first generation iPod Nano (circa 2005) during her ride aboard Tokyo's Denentoshi train line when disaster struck.

An acrid odor flooded the train card and the staff was forced to stop the train.   According to a spokesman for the train line, "When a member of staff went to investigate inside the train, a passenger came over showing him that the iPod she was listening to had burst apart."

The incident occurred Friday morning at around 8:20 a.m. (12:20 a.m. British time).

The train was delayed for 8 minutes while the stench cleared.  For the busy train line, which serves over 1 million commuters daily, that's an extremely rare delay -- the average delay for a train is a scant 20 seconds for some Japanese railways.

Apple is currently in the midst of recalling first generation iPod Nanos in Japan.  Over 60 Japanese owners have received burns or other injuries -- mostly minor -- from their products.

Unsurprisingly, Apple claims the overheating units are not its fault at all.  Apple is passing the blame on to a single battery maker, which it says shipped faulty batteries.  It would not reveal who the supplier was, though.
