mrkt analysis

Need a one summery on Apple Inc. discussing the below topics on distribution:

1. What is the company's market penetration strategy as to distribution - not promotion (intensive, selective, etc.), and how do the channels being used reflect that strategy?

2. Do the channels being used reflect a push or pull distribution strategy?

3. Which of the distribution channels being used do you believe are most profitable, given their relative costs? Which of the channels being used do you believe are not as profitable as others but are still necessary to maintain market coverage? Why?

4. How much control does the company need over its channels (0-level, 1-level, 2-level, 3-level, multichannel, etc.)? How is this need for control reflected in the channels being used?
