Why would I buy a rice cooker?
I come from a culture where rice is our staple and I have a rice cooker. Here are some of the advantages from my perspective:


Rice is perfect everytime – not stuck to the bottom, not watery, not mushy and stuck together, etc.
If you make rice in a pot, and the heat is too high, it will boil and spill over creating a mess.
You can switch the rice cooker on and go do other things, whereas it is dangerous to walk away from a stove.
The rice cooker can be used for other things such as cooking lentils and steaming vegetables.
Rice cookers are cheap.
