Last I heard the lighter limit was one and that this came from the FAA, however TSA was not enforcing it b/c they are spending their time looking for other "threats."

What electronics come out of your bag beyond the TSA requirments is really up to the x-ray operator. If the TSO can't tell what stuff is on the screen then s/he is probably going to have your bag searched. If the TSO searching your bag then tells you that the smaller stuff MUST come out of the bag then s/he is wrong.
