Is the Post-a-Phone an Innovation?

Then I started to think about it as a product, and I started thinking, what problem is this really solving? Suddenly, it started to seem like a solution in search of a problem. I started to read through the comments on the article, and I landed on a comment that brought to light that many (if not most) households now rely on cordless phones which are rendered useless in a power outage. Suddenly I saw this solution without a problem in a new light – as a low cost, small, and lightweight addition to a household emergency kit that could replace a dead cordless phone in an emergency.
