Apple's Mac sales jumped 39% in April over the same month a year ago, while iPod sales were down 17%, a retail research analyst said today.

But it's too early to conclude that those numbers show Apple's new iPad is eating into iPod sales, said Stephen Baker of the NPD Group. "I think it's a real stretch to start saying that things were cannibalized [by the iPad]," he said.

The jump in Mac sales has a simple answer, Baker added. "It was the first month of the new MacBook Pro," he said. "Apple traditionally sees a sales jump in volume after new models are released."
