Why do microwaves have so many features?

I was using the microwave today and I looked at all the buttons I do not use. There were plenty. It seems like such a waste. I only need a power setting (high medium low), time setting and maybe a defrost mode. I suspect that other people barely use all the features of their microwaves. There is always the chance that everyone uses a different 5% of the features. Either way I'd like to see more products with less feature bloat. I am fed up of superfluous features for the sake of "value adding" or making it more "marketable".
