Dear Auntie Ora;

What does it mean when they say "functionality isn't the same thing as usefulness"?

Functionality is Cassie's Ergonomic Flex-Pad Keyboard, with three adjustable wrist supports, Easy-Touch Keys, and full 75-degree adjustable height for comfortable, efficient typing that avoids repetitive strain injury.

Usefulness is getting someone else to do the typing.

Yours Truly,
