I want to know the answer to the following question:
When was the competetive pricing of MacBooks especially effective?
All the background I'm provided with is that "The competitive pricing of MacBooks was particularly effective when rivals charged more for seemingly equivalent Ultrabooks, as this contradicted the established "elitist aura" perception that Apple products cost more but were higher quality, which made these most expensive Ultrabooks seem exorbitant no matter how valid their higher prices were.". Is that enough to answer the question?
Answer: yes
