Microsoft has announced that Office 2007 will not have the ‘Save as PDF’ feature ‘out of the box’ as previously promised for the next release of the Office Suite.
In addition the ‘XPS’ document format will not be directly supported in Windows Vista.
Both features will be available as separate downloads from Microsoft – so despite what some headlines suggest, you will be able to create PDF’s (at least straight-forward ones) from Office 2007.
In many ways that’s no different to the situation right now. There are several products that will let you create PDF’s from Office (or many other programs). One such is primopdf among many PDF creation products out there.
