Wednesday, January 02, 2008 - 10:12 AM EDT"Apple's market share gains in December for the Mac and iPhone are impressive. However, for the last days of December, the numbers are nothing short of spectacular," Net Applications reports in an article posted on their Market Share Website.
First, the month-to-month numbers:
(Product: November Share, December Share)
Mac: 6.80%, 7.31%
iPhone: .09%, .12%
Net Applications reports, "Apple's market share rose 7.5% for the Mac and 33% for the iPhone in a single month. However, the really good news for Apple came at the end of the month. For the last two days of December, Apple had the following numbers:
Product: December 30-31 Share:
Mac: 8.01%
iPhone: .17%
Net Applications reports, "This represents a phenomenal increase of 18% from November for the Mac and 89% for the iPhone. In addition, the iPhone has been taking off in France and the other countries it has been launched in, including an amazing .27% share of web browsing in the United States."
Country: iPhone Browsing Share December 30-31:
United States: 0.27%
United Kingdom: 0.11%
France: 0.10%
Net Applications reports, "Another interesting aspect of this data is that these numbers do not include visitors using Windows on Mac hardware via Boot Camp or other program. Therefore, these numbers actually understate the market share for the Mac. We have no way of telling by how much, however."

It would be interesting to hear how many Macs & iPhones were sold when SJ gives his keynote. We would the be able to estimate the market share. As for installed base, I'm not sure anybody but Apple could estimate that figure.
Phenomenal!
