Thanks for the tip, that bag looks awesome I must say, 4 years down the road, I never found the perfect backpack, just I did build a collection of backpacks that do the work for me.
I personally tend to prefer waist-folding bags, such as the Lowepro CompuDayPack, the Lowepro Rover AWII ( one of my oldest and favorite backpacks to this day ), and the Crumpler Opulent Rooster XL.
Right now, the CompuDayPack is my everyday notebook + small camera gear bag. And the Opulent Rooster was recently purchased in hope to replace the Rover for a camera + notebook bag for when I have to work and carry a decent amount of gear, because even if the Rover is perfect, I need to take the notebook with me, and the Rover AW II isn't a computer-enabled bag. Still, I tried the CompuRover AW, and found a terrible annoying flaw, that is the same as in another of my bags, the CompuTrekker Plus AW ( which is, I don't feel the notebook is proper padded... when it's fully loaded, I feel the weight of the gear pressing against the notebook ).
I got the CompuRover for when I need a ton of gear + notebook. It's a huge backpack, which I never managed to fully fill. Also, because I intended to buy a Medium Format camera, and I needed a bag which would allow me that much. Buying such a huge bag proved to be an illusion, it's too big, and not anatomical enough. It tends to be much uncunfortable after the first hour with it on, and I get home with my shoulders in pure pain.
So, all in all, I have around 7 camera bags, some small, some big, and one HUGE. Depending on my needs that day, I go and fetch one that works for that. Right now, the Opulent Rooster is a great bag, and could fit a Medium Format camera with 3 lenses, but would take you some time thinking on how to fit everything in.
My suggestion, as always when it comes to bags, is to go to a local store, like I did when buying the Rooster. I went for two days, on each, I tested a bunch of bags. Took my camera, some gear, notebook, and I told the shop guys, who already knew me, that I wanted to see how it felt. I tested many bags, until I could rule out one by one, and the one remaining did suit my needs. And before I went to buy, I did a lot of online research based on my experiences on what I wanted ( a Rover II replacement with a good notebook padded compartment ).
For that, there's a site which always helps me, CamBags.com . Here's a link:
