I want to know the answer to the following question:
What percentage of unit sale increase did Apple see from 2005 to 2006?
All the background I'm provided with is that "Figures from December 2006, showing a market share around 6 percent (IDC) and 6.1 percent (Gartner) are based on a more than 30 percent increase in unit sale from 2005 to 2006.". Is that enough to answer the question?
