Apple was effectively accused of lying as it was supposedly impossible that a device could have such a large touchscreen but still get a usable lifespan away from a power outlet. As always, big leaps are hard to predict (classic innovators dilemma). I don't find it hard to believe at all that RIM was doubtful about Apple's ability to meet what they were announcing. They were working on their own products, facing their own limitations - there's no way they could predict what a company with a blank slate would come up with.
