This is a really well designed and very comfortable bag.  I used it primarily as a daily-use bag for carrying my MacBook, powersupply and some binders to and from work.  The strap is very comfortable and can be anchored on either the bottom-right or bottom-left corner of the bag for easy shoulder switching.  I've used this on both my bike and scooter for around town travel too and it does a great job of staying put on your back.  All and all I love the size, pocket layout and strap configuration of this bag.

Unfortunately, the workmanship and material quality is miserable.  In less than two months of daily use (~ 30-45 minutes of carrying around per day) the seams tore out at the top of the bag around the "reinforcement" poly-leather that's around the strap ring as well as the stitching that holds the main compartment zipper in place.  Mind you, this bag wasn't even close to overfilled and I wasn't even using one of the compartments regularly.

I've put in a replacement request with ful, hopefully they'll honor it.  But it is a disappointment.  None of my Swiss Gear/Wenger bags has given me problems like this and they've been through a hell of a lot more abuse (air travel, urban backpacking, hiking...).
