I've been reading this thread with interest!
I've grown up with rice cookers, but never had a fuzzy logic one. One summer my Mum took a rice cooker on holiday with us - we were staying in a motel in a remote town near where Dad was working and she didn't want to eat out too much. She managed complete meals with meat and vegies in there somewhow!
I tried L'Abeille suggestion of cooking polenta in our rice cooker yesterday. Pretty impressive, thought it did develop a crust. We probably could have eaten it before the cooker clicked to warm - it was thicker than when I make it in the saucepan (we have polenta porridge sometimes as it is gluten free)
My Rice cooker (fairly knew) is also a slow cooker. I tried out a recipe on Saturday which was designed for a clow cooker, and used converted brown rice (you fried onion, spices and lime zest first, added stock and them the rice) I didn't have converted rice so I just used the normal brown rice. While quite delicious, it took quite a while and the rice was a bit mushy and afterwards I was mentally kicking myself for not just using the rice cooker setting.
I relate to keeping your old one to cater for crowds!
