Just wondering if anyone has any thoughts on this...

It is common knowledge that with proper storage (sealed containers in the fridge and/or freezer), film can be kept and used well past its expiration date with no ill effects.

But what about disposable cameras?

Presumably it would be better for the film inside them... but what about the camera mechanisms, or even the electronics or batteries in the models with a flash? For the sake of discussion, let's assume that it is a mixture of types - some standard, some with flash, some waterproof... some sealed in their bags, some opened but unused, and some that are half exposed.
