What are some issues associated with using vs. not using a regulator
when designing a consumer electronic device that runs off 2x1.5v
alkalines?

Obviously cost is the issue here. Do most ultra-cheap electronic
devices intended to run off replaceable batteries have regulators?
What drives the decision?

Thanks.
