It's a great bag and you are right, looks like a bag, not a camera bag. I pulled the trigger on the Keystone. I like the idea of a backpack to carry my gear. It also has room for my macbook which made the decision for me. Not sure if I will need to keep the 6 Mil. I will wait for the Keystone to arrive before deciding.
I was wrong a post earlier, the 50D does not do video, which leaves the 7D.
