I have been using this bag for a couple of months now. I use it to lug around papers, a digital camera, a laptop occasionally, and loose ends. I like the way it is built... very sturdy. I like the materials, waterproof/resistant, and as I work in healthcare, I can wipe it down with anti-nasty wipes. Good number of pockets. Cons: it doesn't really have any expansion capability, so while it is big, you can't make it adjustably bigger. It looks like you're ready to paddle down a river, rather attend a professional meeting.
