From what I understand, the problem is that if you put in the wrong kind of battery there is a fire hazaard, so then it becomes a liability issue for Logitech. So the fault really isn't Logitech it's our litigious society. That being said, to be treated like an idiot unable to replace a battery with the correct type does appear to be an insult. After all, we were smart enough to buy the keyboard, but not smart enough to replace a battery. Hmmmm.
