RROD = a multitude of possible errors, generally drive failure or overheat/motherboard failure.The new slim has considerably better cooling architecture, and more efficient (lower power) cpu/gpu so it is arguably more stable in those respects. As for general hardware faults, thats anyones guess. Vomiting on a plate is better than the original 360's 30% first year hardware failure rate....so I would say yes, the new ones must be better. One can't judge the odds of failure or Mean Time To Failure MTTF for the new units since they're not old enough to gather enough data. One cannot yet predict the failure rate accurately.
