No. If you have to carry it for some reason it will be heavier than a regular backpack. And I'm usually in a rush when I'm out, so it would be faster to just carry the bag than drag it around.
A girl in my grade uses one because she said a normal backpack can't contain all of her showchoir and performance materials. That sentence alone is reason enough not to purchase one.
I used to use one in high school because of back issues but rolling it around was so loud and attention grabbing that I almost never actually rolled it around.
