As far as a typical payload, I have found that the ID is just big enough for my needs without being too big to manage. I usually carry a 6x9 sketchbook, a lunchbag, and a horizontal freudian slip with the required folders, papers, etc. in the main compartment. The smaller pockets are loaded with the usual day-to-day extras: sunglasses in a case, iphone, iphone accessories (in a padded pouch), mints, pack of tissues, and my contact lens accessories as needed. I also carry my work laptop (IBM Thinkpad T60) and power brick when required... but usually I don't carry that in a laptop sleeve. I do have a TB soft cel for it, but it really takes up a lot of space in the bag that makes it difficult to fit much else in the main compartment - some folders and a book or two.
When I travel, a whole host of options go in the ID: a couple of books, light jacket, small umbrella, rain hat, extra bottles of water, a camera... the size is perfect for flexibility. I make frequent use of the o-rings as well to strap on additional pouches or lanyards for keys and the like.
I'll echo David's comments about size in the main compartment: a Freudian slip or a laptop does take up much of the available room. If I need to carry a lot of big stuff, I go to my Brain Bag.
I hope this helps!
