I don't have any special insights for microwaves, but I do have a question...

What's the deal with all those buttons on microwaves? Don't get me wrong (I've been gotten wrong before, and I don't like it), I love microwaves, but are those buttons all necessary? Do they even do anything? I'm sure that if I press them, they will beep and perhaps display something but it will do the exact same thing as if you hadn't pressed them.  Do you ever use the supposed myriad functions of your microwave?
