Do all the bag names ("satchel" "hobo" "shopper" etc.) correspond with specific sizes and other characteristics? i.e., if I buy a "shopper" will it always be the same size as another "shopper"? Or do the names indicate the type of strap? Which kind of bag is big enough to hold, say, an iPad?
And does anyone have a bag that actually stays on their shoulder while they shop? (Mine will hang on my shoulder, but it repeatedly falls off as I'm trying to put children in carts, re-hang clothes on hangers, unbuckle seat belts, etc.) For all you multi-bag-ladies, do you move all your stuff from one bag to another? Every day?
