As soon as I got this for my birthday, I quickly switched everything over from my work bag to this bag.  The fabric is perfect for my commute (train, bus, walking through the city) and this bag is big enough for me to toss my netbook, umbrella, and extra pair of shoes in the big section.  I love all the extra pockets which is very helpful - just wish that they had a place for me to put my pens, too.
