Given this is a hit for the e-cig community, and for the man and his family (hope all is well). There are many instances of batteries exploding, catching fire, etc. in many, many other electronic devices. Any device with a battery can result in a very nasty fire/explosion (laptop, cellphone, etc.)
Why stuff like this doesn't make it into the news any more is beyond me. The sad fact is there are a lot of people who will soon be losing massive amounts of money as the e cig community continues to grow and will do just about anything to not see that happen. So like someone said above (hopefully all of this was not said, didn't read every post here) I would rather add another possibly explosive device to my arsenal of already dangerous daily objects rather than have to deal with all the nasty, negative side effects of cancer sticks.
