A third-generation, 30-GB iPod, serial number AP356372, died early Monday morning at age 2. 'I'll never forget all the great music it used to play during my workouts,' said the late iPod's owner Sarah Zartman at a brief memorial held over the junk drawer. 'It was convenient, portable, and really priceyalmost $500.' Zartman said that, had she known the iPod's lithium-ion battery would have such a short lifespan, she might have spent more time listening to it. AP356372 is survived by a BlackBerry.
