Not content with simply destroying our laptops and cellphones, those evil little lithium ion packs have just escalated the human-battery conflict once again by sacrificing many of their number to lay waste to an entire building. Actually, it's not clear what started the fire at Matsushita's Li-ion plant in western Japan on September 30th, although we suspect a cadre of malcontents decided to self-detonate after taking a cue from their comrades at Sony. What is clear is that an unnamed Pentax digital camera -- probably one of the recently-announced Optios -- will be delayed because of the fire, with its launch being pushed from next month to February of next year. Hitting us in the gadget, right where it hurts: smart move, clever foes, smart move.
