Calpak's backpacks, messengers, and laptop bags have all the features students and adults need such as comfortable padded shoulder straps, pockets for your calculator, pens and pencils and more pockets for all the other stuff you carry. The Quantum is a great rolling briefcase that fits most 16" laptops and has multiple pockets for organizing.
PROS: I'll start with a positive comment about the color options. I got this bag in green. Olive is a good descriptor for this color. I was so tired of black rolling bags, and green is my school's color. From a functional perspective, the two main compartments are room enough for three classes of books and folders. I use the large outside pocket to organize my white board markets, colored pens, stapler and other office supplies I need in the class room. I'm a professor that teaches in several classrooms on a given day, so it's essential that I can "travel" between rooms quickly and easily. The bag carries everything I need to get through a day of classes. It also rolls easily.
CONS: The laptop sleeve included is very small. It fit my first generation iPad with a little extra room all around, and my mini-computer, but it certainly won't hold my 17" computer, or probably not a 15". The pocket (in the case, divided section within the rear zipper area) that holds the laptop sleeve may hold my 17" computer, but I don't use my laptop around school as I have my iPad and classroom computers.
