I got this bag because I travel a lot and wanted a carry-on bag that could double as a laptop/work bag.  This fit the bill well!  I've just come back from my first international trip with it and am very happy with my purchase.  I can put my wallet, phone, cosmetics, etc. in the center section (which zips closed) and my 13" Macbook fits in either of the side pockets (they snap closed) along with files, a shawl, magazines and more.  Inside each of the 2 large side compartments are small zipper compartments on each "wall" of the compartment.  These smaller compartments can hold such things as a passport, gum, pens, phone, and kleenex.  The only difficulty was in remembering which one of the 4 pockets I'd put something in!  The main compartment also has a zippered compartment and a place to put smaller things as well.  It also has a key strap to attach your keys.

The bag is extremely lightweight and the straps are long enough to put on your shoulder but short enough for a shortie like me to carry in my hand without having the bag drag on the floor (probably only those of you under 5'4" can relate to this).  I like the giraffe print I got because it doesn't show dirt.  The only downside is that because it holds so much, it can get heavy and the straps are not long enough to carry it messenger-bag style.
