I use my PDV and so for me, it's perfect. Especially for lectures or seminars, it's lightweight and holds my laptop (if necessary) and textbooks and stationary and other bits & bobs e.g. my wallet so yup, it's perfect! But as suggested, BH or neverfull. A girl in my seminar uses a lockit or the antigua cabas and it works for her! I guess it depends how much you carry!
