Rose: I was thinking that the PC's had this ability too with Adobe Distiller - which I thought use to be free. Was looking now, and it is only available with the full (paid) version of Adobe.

It works pretty cool - in a word (or whatever) file, go to print, print it to the adobe distiller, and it would save it as a PDF - so not really "edit" PDF's, but would let you create documents in other formats and save as a PDF.
