Nielsen's "Usability" and Some Questions (Part 2/3)

Memorability, on the other hand, is one of those elements that might not seem immediately obvious when user-testing first occurs, but many of us have experienced the loss of system proficiency after not having used a product for any extended period of time. I continue to experience some amount of anxiety when moving between Adobe products when the quick-keys for certain shared functions is not the same or when the interface (eg. in Illustrator) is different between a Mac and a PC. Additionally, whereas errors are also easily recognized as a hindrance to production, subjective satisfaction would seem to be a derivative of the other attributes for usability.
Does subjective satisfaction deserve to be an individual element or is it a derivation of the other attributes of usability?
