[Nomentatus]

I love the movie line, and I too long ago learned that user feedback about software I'd written could be nonsense or pure ego, BUT - I think you missed the "other elderly" point at the heart of the complaint. I'm over sixty and I'm constantly stunned by how computer illiterate other sixty-year olds are (and yes sometimes thoroughly flummoxed by UI changes myself.) If you're twenty such changes are trivial to overcome - you just ask your buddies what they did. Above sixty - your friends have no idea. Google usually isn't a solution for such general questions, either, particularly if a "magic term" is needed that they won't know. The young turk UI programmers, seem to assume everyone has better than 20-20 eyesight, single-pixel hand-eye coordination and a lot of background knowledge and UI intuitions that elderly people don't have - because they may update their equipment and software only every decade or two!

I suspect the answer may be a secondary, vastly simpler interface that can be maintained as a fallback for the elderly, without breaking the bank.
