I recently needed to edit a file for which I had the PDF version only. That was the time where the Sun PDF Import Extension is becoming really handy.

What you need is OpenOffice.org Version 3 and the import plugin. A PDF will then be opened in OpenOffice.org Draw and you can edit the file’s content.

This isn’t quite the same as using writer directly, but it works very well if you don’t want to change larger parts of the document. However it’s not perfect and opening a large file of nearly 70 pages took quite a while.

So while waiting for your most recent eBook to be opened, you should give popular OpenOffice extension a try.
