And it doesn't even have undergone any independent security evaluation.

Smart cards (if done well) protect from unwanted key duplication or
disclosure. It's much harder to break into someones home to steal the
card than it is to steal a file and a number of key strokes.
Of course a smart card can not protect against malware on the host
computer, but it can prevent that the key is gone after malware has
infected the host. If my card is suddenly missing from my desk, than
that is much easier to spot than an illegal copy of my key file - which
I can't really detect.
And we are talking about the average user that can not easily control
what processes are running on their computer and if it's good or bad.
For them it's much easier to lock important keys away in their desk than
it is to keep a computer free from malware.
