I always use just two bins. One for my laptop, another for my jacket, DVD player, MP3 player, cell phone, & keys.
I have been traveling with a DVD player since late 2004. After the first 2 or 3x through where I left the player in my carry-on, and the carry-on was pulled for secondary, I learned my lesson. Ever since, I have always been taking the DVD player out of my carry-on, even before the new electronics policy.
