I hate bags with too few pockets and slots. I don't want to spend forever digging through my bag like I'm digging for a prize in the cereal box. I want to reach in, grab what I need and go on with my day. My favorite work bag has a built-in organizer with different sized compartments along with several zippered pockets around the outside. If you like to switch bags often, buy one that has at least one large section that you can insert an organizer in. It's a major time saver, especially during hectic work days.
