Yes being an EE it makes me nervous when I walk around the house and can count over a dozen devices sprinkled around the house that are actively charging LiIon batteries.

3 tablets, two laptops, 4 phones, a quadcopter, cordless screwgun, flashlight, the list goes on.

And THEN the samsung battery problem - dont get me started.
When I fisrt heard about this i was quoted as saying "They had BETTER NOT come out and say that they have a software fix for that!!"

Then they came out the very next day saying "we have pushed a software fix to all the phones that will limit the charge to 60% which will reduce the chance of a fire"

YOU DUMBASSES! that means that some rogue hacker can push a patch that will tell all of the phones to charge to 150% and we will have fires breaking out all over the world.
Battery charge control should NOT be reconfigurable via a software patch.

A "minor software patch" was what caused the loss of the Mars Global Surveyor spacecraft when the batteries BLEW UP because some key fault protection parameters were inadvertently overwritten by the patch.
