The "ideal bag for a mobile life style" raises the question, what tools do you carry with you?

It varies by what tools are necessary for you to do whatever it is you do, of course, but I think it's an interesting question.

I have two bags -- one small purse and the bag that carries my laptop. My purse can go in the laptop bag, or if I don't take my laptop, go alone. I'm going to list what I always carry with me after I do an inventory.

Anybody else?
