NPD issued its sales reports on April that showed that Mac sales were up 39 percent year-over-year, suggesting that the iPad isn’t cannibalizing sales of Apple computers. The iPod, however, continued its downward slide with a 17 percent drop off, suggesting that some iPod consumers might be upgrading to the iPad instead.

“April NPD data gives us the first sign of the degree to which the iPad cannibalizes iPod or Mac sales,” writes Piper Jaffray analyst Gene Munster. “From the early NPD data, it appears that the iPad has a minimal cannibalization impact on Mac sales, and could be slightly cannibalizing iPod sales. Given the [average selling price] (4x) and margin profile of the iPad, we see this as a net positive for Apple’s business.”
