My friend exzim asked what backpack I have. This is it. It is a Canon brand. I spent hours going through Houston Camera Exchange looking at their hundreds of options, and this one fit the bill. It was in a middle ground of size. I can get my SLR and other camera stuff as well as the computer power supply and a portable hard disk inside it and the mini fits in a flap on the cover. I use some foam padding when I put it in there. Here is a link to the Canon product description:
