Rice cookers as simple machines?... Ohh.. but I beg to differ... may I direct your attention to the Zojirushi NS-ZCC10 5-Cup Neuro Fuzzy Rice Cooker? The reviews would indicate that it's the best thing ever. The manufacturer describes the machine as as having "Advanced neuro fuzzy® logic technology; multi-menu settings--brown rice, semi-brown rice, sweet rice, mixed rice, porridge and sushi rice; pre-washed rice (rinse free rice) cooking function; easy-to-read wide colored LCD; detachable and washable inner lid; start & completion melody signal; reheating cycle; extended keep warm cycle; stay-cool side handles makes removal of inner cooking pan quick and easy."
