What Backpacks/Bags do you use?

I know I posted that my Axio is really nice, but the Ogio No Drag bags have one feature that I wish I had. If you live in a high density area, a backpack that opens from the inside is MUCH harder for someone to open and snap your laptop. My commute can be pretty ugly and I carry mace hooked onto my sleeve adjuster. This would make me feel more secure.
