Strong sales of Apple's Mac computers helped Apple report strong earnings for the second quarter of 2008, despite weak growth in iPod shipments.

The company's net revenue was $7.51bn for the quarter that ended March 29, a 43 percent rise from last year's second quarter. Analysts polled by Thomson Financial estimated revenue would be $6.96bn for the quarter. The company's net profit was $1.05bn, a rise from the $770m it reported last year.

Apple shipped 2.3 million Macs, a 51 percent rise in units and 54 percent revenue growth from the year-ago quarter. It sold 10.6 million iPods, a 1 percent growth in units and 8 percent growth in revenue from a year ago. iPhone sales for the quarter were 1.7 million.

The company is excited about new products in the pipeline, said Chief Financial Officer Peter Oppenheimer during a call to discuss the results. When asked about the possible release of a 3G iPhone, Apple executives declined comment.
