While that's the most talked about scenario nowadays, I've found these 
(unsigned) checksums extremely useful for proving that a problem 
installing NetBSD was in fact down to data corruption.

The person doing the installation didn't believe me that there was a 
problem with the ISO image until I had him actually verify the checksum.

So I'd say, even without digital signatures, checksum files *are* useful.
