Sales of Adobe Creative Suite are yet to peak bcause many customers are yet to move to Mac OS X, says company CEO Bruce Chizen.

Chizen told Dow Jones: "Many people are still evaluating the move to Apple's OS X operating system, which the suite requires.

"Other customers are talking extra time to decide which version of the product to buy and to debate the merits of the suite compared with individual Adobe products, such as Photoshop and Illustrator."

The news comes as Adobe celebrates record earnings figures for its fiscal first quarter that ended on March 5.

Adobe achieved record revenue of $423.3 million, compared to $296.9 million reported for the first quarter of fiscal 2003 and $358.6 million reported in the fourth quarter of fiscal 2003. This represents 43 per cent growth year-on-year and beats Adobe's revenue target of $380 to $405 million.

Chizen said: "Our outstanding quarter was driven by strong global revenue from the new Adobe Creative Suite and record revenue from our Intelligent Documents business. This highlights the increasing relevance of Adobe technology platforms to creative professionals and enterprises worldwide."

He added: “Given the impressive start in Q1, we have raised our fiscal 2004 financial targets.” Adobe has raised its annual sales growth target to between 14 per cent and 16 per cent from a previous forecast for 10 per cent.

Chizen added that first-quarter results were strong overseas. Adobe received 57 per cent of its revenue from outside the US in the quarter, compared with 50 per cent last quarter.
