Every once in a while I'll wake up, unplug my iPhone from it's charger and go to work, doing my normal planned routine, and have it die before I'm able to get back home to recharge it. Does that mean that my iPhone is a failure and I should sue Apple for failing to deliver on their promise of X hours of battery life? No. That's stupid. In agreement with you, sometimes things just don't work as desired, but the usefulness of the device isn't diminished, it's just altered.
