I want to know the answer to the following question:
How much revenue did iPod sales account for in Q4 2008?
All the background I'm provided with is that "The continual decline of iPod sales since 2009 has not been a surprising trend for the Apple corporation, as Apple CFO Peter Oppenheimer explained in June 2009: "We expect our traditional MP3 players to decline over time as we cannibalize ourselves with the iPod Touch and the iPhone."". Is that enough to answer the question?
Answer: no
