Adobe: A Powerful Player in its Field

With millions of consumers, Adobe owns a real power in its field but also on the entire IT market. Apple faced it as most Mac users relying on Adobe solutions have delayed the purchase of a Mac Pro till Adobe releases native MacIntel or Universal binaries versions of its blockbusters applications? Some analysts predict that Apple will experience a massive request for Pro hardware models when the native CS3 will be released, but it is still not clear if it will compensate the currently lower than expected sales of Mac Pro.
Adobe is also going to pressure Microsoft. Indeed, it has officially announced that Vista compatibility and support will be available only via update to be released by mid 2007, but it will not apply for all applications. New version of Adobe key applications are being developed, and will then be Vista compatible. hereafter is an example of such details:

Will Adobe update currently available products to support Windows Vista?
Adobe has an extensive portfolio of products, each with different schedules for fully supporting Windows Vista. For example, Adobe has already released free updates to Adobe Photoshop Elements (version 5.0.2) and Adobe Premiere Elements (version 3.0.2) to deliver full compatibility with Windows Vista, and it currently plans to release a free update to Adobe Acrobat 8 and Adobe Reader 8 in the first half of 2007 to support Windows Vista. On the other hand, Adobe is already preparing to release the next versions of its professional creative products, including Adobe Photoshop, InDesign, Dreamweaver, Flash, and After Effects, in the Spring and Summer 2007 and does not plan to issue updates to current versions of those products for Windows Vista compatibility. For more details, please see specific products sections in this FAQ.

So to get the CS3, you will have to migrate to Vista and a more powerful hardware. In addition, Adobe Acrobat is not fully compatible with Office 2007, and a fix is not expected before mid-2007. Is it a new step in the war between Adobe and Microsoft around the PDF format and its modified adoption by Microsoft in Office 2007?
