Alright, I'm a brand new IPad owner and I already issues sitting it down for more than a few minutes. But beyond the OtterBox... I need a proper sling to use. I want to keep it on my person without resorting to a man purse. I'll describe what I'm looking for and pray someone can help me. The only place I can foresee is the small of back. I'm curious if someone has seen a backpack that loads from the side. Something I could simply reach behind me and pull it out. Horizontal loading. Possibly one that is a single strap. Anyone....?
