Okay, I love bags and I have always wanted a Timbuk2.  That being said I purchased this bag at a great value and I am happy that I did.  I am an educator and I usually carry a back pack with all of my gym gear etc. as well as my grading materials and lap top (see the Osprey Nebula).  I also have to go to many professional meetings at the District office and with various administrators so I wanted something a bit more professional so I chose this bag.  I love this messenger bag, the medium is a good size for a "daily driver" and the build quality is phenomenal.  So why not 5 stars?  Well it comes down the buckles.  They are a pain in rear and are the worst part of this design.  If the buckles made more sense I would give this bag five stars.
