After realizing UX includes the wonderfully apropos tag "physical" I am hoping to get some insight into something that has long been a conundrum for me: when the packaging around a ream of paper switched from paper (where an experienced hand could open a ream with a single snap and unwrap it in a couple seconds) to plastic (which now requires scissor or knife to open).
I suspect it likely cuts down on spoilage due to mishandling, moisture, etc., but was that really the motivation? What about the cost of good will? This seems like a tremendous step backwards in terms of convenience to the customer in favor of some (?minor) cost savings for the manufacturer.
