Though you write PDF documents without Adobe Acrobat, there aren’t many choices for editing PDF files. Most PDF editors are either commercial or offer very limited functionality.
All this is expected to change when Sun releases OpenOffice 3 in the next few months as it includes native PDF import and export features. See the slide above.
You will be able import PDF files into Draw (PowerPoint), perform the edits and then export them as hybrid PDFs meaning you can edit the PDF files back again in OpenOffice.
OpenOffice 3 will be available on Windows and Mac. It may not have all the PDF editing features of Acrobat but may still satisfy the needs of most users who only require basic editing.
