I have one, and I really like it. It is a very nice size, and holds all my stuff comfortably. It does have a some structure to it, so I don't feel like I am fishing for my stuff. It is not a super squishy leather, but it is nice quality and seems like it will only get better with age. The strap has a very comfortable drop. The suede lining is very nice as well.
The one caveat I have for you - several of us bought this bag from their website-launch sale, and many of this particular bag had issues with the rivets that hold the straps on the bag. Depending on the person you are buying it from, they may have had the rivets replaced and fixed, or it may be broken. Also, depending on how they went about having it fixed, the rivets may not match (if only some were faulty). Just an idea of what questions you might want to ask the seller.
If you really like it and the price is reasonable I would consider it - only one rivet was an issue on my bag - the rest are fine and I have had no probelms with it since - and I do not baby my bags. I was able to get the rivet replaced very professionally (and cheaply) and a local shoe or leather place - it was a good deal for such a well-made bag.
HTH!
