What product is used in OSX to edit word or openoffice documents and also works with PDF? I want to be able to copy portions of PDF file and paste into another document like MS Word format document. The important thing is that any portion that is copied must preserver original formatting fonts etc. when it is pasted into my document. So what product is out there on the writing side and what product is out there on the PDF side?
Preserving the layout and appearance from text in a PDF when copying it to anther text processing tool is almost an impossible task, both on OSX and Windows.

I'd suggest two things:


Export to .rtf. In Windows using Acrobat Professional you can export as .rtf, which can be opened by Microsoft Word (among others) and is (sometimes) a close approximation of the layout and still allows for editing the text.
On OSX there appears to be tools that allows exporting to .rtf as well, like this one: File Juicer (never actually tried or used it). You can then open the .rtf file using Word, OpenOffice, etc.
screenshot - However, if post-editing text is not of your concerns, I'd go for a screenshot from the PDF that you paste into whatever editor you are using.
