Well I have always cooked rice on the stove, and over time I seem to have perfected the art of doing so. I have never used a rice cooker before, but now that I am reading about it here, it sounds like a good piece of cookware to have. When cooking rice I always have to be back and forth checking to see how it is cooking, if it still has water, if I need to lower the stove, add water, etc. Since a rice cooker would save me having to do all this, I think it must be rather convenient. The thought of it cooking faster is not a bad thing either.
I cook rice on a regular basis. The only thing is, I tend to use peas more often than not when I cook rice. I would cook the peas to a certain texture and then add in the rice. I don't know how this would work with a rice cooker. I guess the peas would have to be cooked separately and then mixed in with the rice afterwards.
