Same here. I just got mine not that long ago though (the MM from MOCA) and I've put notebooks and a textbook in mine and it's perfect.I have a Neverfull MM & used mine all summer with a bunch of stuff in it which made it heavy. I also have used it as a work bag & put a small laptop & papers/files in it. It never dug into my shoulders, but I know I've heard some people say it dug into theirs. But for me, it didn't big into my shoulder at all...it was comfy!!
