and, if said at *all*, should be noted as "personal opinion".

Although a "purist" might feel this way, I believe there are many
circumstances where an electric pump will keep a piano playing which
otherwise might just sit.  For instance, from time to time I experience
very painful lower back problems.  Should I be denied the use of my
piano simply because I am unable, physically, to pump it?  I'm sure
there are many who may fit this category.

Also, although not technically capable of making music by itself, I
think that at least a passing mention could be made of the Pianocorder.
