It's always right. When I'm cooking a whole meal, I can easily forget about the rice, and end up with burned bottom and mushy top.
It's always perfect. The variability of my stove burners means that my rice on the stove never comes out exactly the same. With a good rice cooker, you never have under or overdone rice.
If you eat rice every couple of months, a rice cooker is pointless. I eat it two or three times a week, and I want it to be good every time and without me having to think about it (because rice is what goes under the food I'm making on the stove, so I'm too busy chopping and cooking to worry about rice).
