If noone knows you're using it, the device might even be better than a software RNG.

I don't think so. The PRNG will at least be less biased.

That's only assuming that the PRNG hasn't been backdoored or otherwise compromised by the NSA. If it has, damn near ANY hardware RNG will be better than it. If not, then you're right.
