What are the uses for microwaves?

Microwaves can be used for many things, but mostly heating things up that need to be re-heated or things that can actually be cooked easier and more efficently like rice and sometimes, certain tipes of steamed vegitables. Other then that, the only thing I can think of off the top of my head is to heat up milk for infants and to heat up water for tea/chocolate milk/etc...
