I, too, would find it useful -- for me (although I do not hate myself).

Surely, you know an alarm clock. Usually, it gives an audible signal
when it is time to do something. A computer can in principle be used
as a flexible alarm clock - but it is not so easy with the audible signal...
An audible signal has the advantage (over a visual one) that you can
recognize it even when you are not looking at the screen (because you
are thinking).

Unfortunately, I had to give up. My new computer lacks a working
speaker...
