Here’s a good group of statistics from Mary Meeker at Morgan Stanley.
In the second quarter of 2007 Apple’s revenues were as follows: 47% Macintosh range of computers, iPods 40% and iTunes 11%. Fast forward to the first quarter of 2010 and the revenue figures looked like this: iPhone 40%, iPod and iTunes combined 24% and Macintosh computers 28%.
One other delicious bit of data. If you look at a graph showing sales of PCs against sales of smartphones globally you will observe that sometime in 2012, smartphones are due to start outselling PCs. So is the PC dead? I don’t think so.
