That X-ray picture suggests there are technical advantages (if not outright needs). Even if it was unnecessary, it makes the iMac more interesting and distinctive. It would look like any old monitor otherwise. Plus, it's a handy spot for post-it notes (even if they don't stick as well these days).
Quite apart from that, I don't see the problem. Who stares at the bottom border of a screen? I also wonder if the very use of the word 'chin' is part of what people object to. It's a nice shiny strip of glass. Not a chin.
