This is my first amazon review simply because I am so unhappy with the previous comments.  I almost did not purchase this bag because the other reviews say it is "too big" that is simply not true.  I fell in love the second I opened the box.  It was very carefully packaged with every inch of it covered in multiple strips of protective plastic.

I transfered my laptop, power cords, blackberry, and notebook...and the bag was nearly full.  This is definitely not a "weekender" bag, unless you pack lightly.  I would consider this an "overnight" bag, yes. I love this bag and plan to purchase more colors.  The dark brown is divine and I am thinking of purchasing another color for when I travel, like red so it does not look like everyone else's luggage.

Again, I say...if you carry a laptop to and from work (school) everyday and have corresponding power, notebook, and other small essentials then this is the perfect bag for your needs.  I was able to put in all the essentials, my small purse and a small tupperware for lunch...I am super happy with this purchase and plan to buy at least ONE more color to add to my collection.
