Apparently the other 50% agree with you.
A backpack works well for me but it has two stabilizing straps along with the shoulder straps. If I didn't have it adjusted fairly snug to make sure it stayed put, it would bug me too. I also do not care about getting warm and sweating. I use my commute as a work-out. Not everyone does of course.
