Overall this is a great bag being held back from being the ultimate bag by a few issues...
The bag looks great. not too heavy. Has a great strap with a nice adjustor. I really like the custom colors I selected. The magnets for keeping it closed are awesome!
The main storage area is well sized and holds its shape well, which is a big bonus as i tend to have a few file folders with papers that i don't want bent.
I also really like that it is free standing so i don't have to lean it against something all the time like i have to with other messenger bags.
Areas to improve...
The side pockets are so small that you can't use them for much of anything. I usually use the side pockets to hold my travel coffee mug, a mini umbrella, or a can of pop. I can barely squeeze an umbrella in and thats it. There is no give to the opening and it is very small, so i have no idea what you are supposed to use them for.
The back zipped area is great, but only has two larger pockets in the middle. On either side are 3 pen-sized pockets. I feel like there could have been more versatile storage options in here.
The main storage area doesn't have much in the way of storage pockets for smaller items. Becuase of this I purchased an extra utility pouch to store odds and ends in and keep that in the main pocket. In hindsight i should have bought two of these.
The 15" laptop sleeve is just the right size for my 15" MBPR, however it is almost too snug as i have to be very careful sliding it in when i have my USB mouse adapter plugged in. Even an extra quarter inch of width would make it much easier to slide things in and out of.... and I also didn't realize that a sleeve came with the bag so accidentally bought 2 of them.
Despite these gripes, this is still the nicest bag I've owned, and I'm a bit of a bag junkie. I really really really like it. If these improvements were added to the 2.2 version, I'd probably buy that too. : )
