The compelling use case is not having to store your private keys on your computer, even momentarily. Of course, if you don't deem that too risky, a hardware wallet will do nothing for you. That being said, I believe storing private keys on a general computing device is very foolish and you will likely find out the hard way. I wouldn't store any more in a hot wallet than the amount of cash I'd be comfortable walking around with in my pocket.
