Apple's iPod continues to be fantastically popular

Releasing its results for its fiscal first quarter, it made a net profit of $565m (�320m), up from $255m a year earlier. Revenues rose 64% to $5.75bn.

Sales of Apple's computers totalled 1.25 million during the quarter, below market expectations.

Apple also disappointed with its second quarter results projections.

Forthcoming products

"We are thrilled to report the best quarter in Apple's history," said Apple's chief executive Steve Jobs.

Some analysts believe Apple needs to renew its focus on computers

"We are working on more wonderful products for 2006, and I can't wait to see what our customers think of them."

The reaction of analysts to the results was however more mixed.

While many were impressed with the figures, others cautioned that Apple still wasn't seeing enough growth in sales of its computers.

Over-reliance?

"Historically, the Mac [computer] has been the primary revenue generator - even though all the news has been about the iPod [over the past few years]," said Nitin Gupta, analyst with the Yankee Group.

"At this rate of growth, the Mac is not going to be their primary revenue driver.

"If they become too dependent on iPods and digital audio players that's a risk over the long terms.

"It's going to be hard to maintain those iPod shipment numbers."

Apple also disappointed analysts with its predictions for its current second quarter.

It estimates it will achieve revenues of $4.3bn, below market expectations of $4.8bn.

As a result, Apple shares fell in after-hours trading in New York.

The computer and electronics firm has now sold about 42 million iPods since their introduction in October 2001.

Apple, whose shares more than doubled in 2005, also recently announced that its computers would soon be using Intel processors for the first time.
