I'm a university teacher and I really like the concept, but if everything you carry is no thicker than a piece of paper then most bags will be completely useless to you. I have a laptop, an iPad, a wallet, some medication, some chargers and supplies. On the way from office to classroom, throw in three dry-erase markers and a set of graded paper and you'll run out of room to use it. And I would imagine that even if you only use it for your laptop, you would find that all the pockets are too small and there are too many of them.
