The iPod halo effect had a positive impact on Apple's financial results, according to two analysts.

Merrill Lynch analyst Steven Milunovich told MacMinute: "There is quantitative proof of the halo effect," suggesting that the music device was behind increased Mac sales.

"iPod is bringing new users into the tent, benefiting not only Mac sales but also peripherals and software," he said.

Piper Jaffray analyst Gene Munster agreed. He said: "Our confidence in the halo effect has increased based on Mac sales of 1.07 million units in the March quarter compared to Street expectations of around 970 thousand units."

"We believe the halo effect is the primary driver of upside to Mac units. We expect the halo effect to accelerate in 2005 as the total installed base of iPods increases from 10.3m at the end of CY04 to an estimated 35m by the end CY05," he told MacMinute.
