Ever since Apple Computer (AAPL) introduced the iPad almost a year ago, there has been a concern among some that strong sales of iPad would cannibalize sales of PCs. After all, who needs an extra laptop or netbook if you can just do the same thing on an iPad?
While the strength of the iPad may be hurting some PC sales, it's hard to argue that iPad sales have hurt sales of Macs. The chart below shows quarterly Mac sales since 2007. As shown, in the three quarters that AAPL has been selling iPads, the company has also seen its three strongest quarters of Mac sales.
With numbers like that, it's hard to say that iPads are cannibalizing sales...of Macs at least.
