What's with all the buttons? My rice maker is about to die, and I've had it since 2007. It has one button: cook. I looked at a Zoji and there are so many settings. Plus every type of rice has different ratios of water, which vary with quantity, so how do those settings do anything useful. I'm not too proud to admit I'm intimidated and don't want an overpriced "jack of all master of none".
