Let's read what Apple CEO Tim Cook said four days ago:
"From there, Cook tackled a much-discussed topic in recent quarters: whether or not the iPad is cannibalizing sales of traditional PCs. “I think that iPad has cannibalized some Mac sales,” he conceded. “And the way that we already view cannibalization is, we prefer we do it than have somebody else do it.” Because of that, he added, “We never want to hold back one of our teams from building the absolute greatest thing, even if it takes some sales from another product area.” "
