True, for things like random character generation (e.g., Morse code
practice).  I don't expect it applies to random noise generation.  But now
that you've said it, I will have to try it and see if I can tell the
difference :)

As long as I'm here I'll mention the application.  One day I decided to use
some noise to drown out that of the office. So I sent the low bit of the
result to a port bit, ran that through a resistor to some headphones, and
presto...instant background noise.
