Sometimes the water u want to drink is just not the right temperature. There should be a cup where you pour the water in and type in the temperature you want it to be. And that would help if someone needs the water to be boiled or very cold. They don't have to use icecubes or microwaves...

Reward: a cup for me please

This is technically easy to accomplish but may be difficult to produce economically. Your cup would have to incorporate both a Peltier device for cooling and a heating element for heating. There is a very similar topic on this site that covers this subject. It plugs into an automotive cigarette lighter socket. This similar topic also has a .JPG graphic attachment of the device that's already on the market.
