One thing to consider is that plenty of packaged foods seal their bags with pure nitrogen to keep the humidity under control and eliminate oxygen ageing the food in storage. It's the same reason why a bag of chips can have some quite lengthy expiration date and still taste fresh when you open them but leave them sitting in your cupboards for a while and now they're noticeably less fresh. Having some sort of chip dispenser (or cereal, goldfish, whatever) would make that quite a bit harder to deal with.
