Adobe and Apple's relationship is "like any marriage, good and bad," says Adobe CEO Bruce Chizen.

Chizen told Cnet: "Our relationship with Apple is a great one, even though Apple's cutting us out of some markets. It's an important relationship for both of us to maintain and make stronger, knowing that there are differences.

"My relationship with Steve Jobs continues to be extremely strong – we communicate on a regular basis. Where we compete, we've agreed to compete. Where we partner, we partner aggressively. At the end of the day, we both have a vested interest in doing what's right for the creative professional customer."

Chizen also spoke of Adobe's plans to expand the PDF format into a multiplatform foundation for viewing and sharing corporate data, and whether pushing into the enterprise will make the company a potential target for Microsoft, especially in markets like electronic forms.

"The market we're going after is different from the market Microsoft is focused on. We're focused on those customers and those industries that care about the reliability of the document outside their environment, and they want to have intelligent documents that cut across platforms - and it's where good-enough – meaning HTML – is not going to meet their requirements," he said.

According to Chizen, Adobe decided to push PDF into the enterprise market following pressure from customers: "During about 1998 or 1999, we started having customers ask us to do more around the PDF and Acrobat Reader.

“We realized that if we could provide more applications around the PDF as the file format and Acrobat Reader as the rendering platform, not only could we make many customers much more efficient and productive, but it could be a valuable revenue opportunity."

Chitzen goes on to admit that with previous releases of Acrobat Reader they have "tried to accommodate more and more capabilities – the ability to handle more dynamic content such as moving images, still images and slide shows and to incorporate XML data - and we haven't been as efficient as we probably could have been and would like to be".

But he insists that issues such as loading times are set to improve with the next release: "You'll see that addressed in the next release of Acrobat and Adobe Reader. The goal right now is to significantly reduce the launch time."
