iThink .. the most benefit with apple products will be in alternating cycles
iPhone 3G to iPhone 4 to the next iphone
ipad2 to ipad 4th gen
even with macbook pro's every alternate release is a better bump in features and more value for money.
but hey .... i have seen hard core apple fans (moi-bitter half) bye every release and they also have prefect timings when it comes to pass on / gift / sell the old ones.
