Additionally, Photoshop, Illustrator, and InDesign, three of the four top-tier Adobe applications I own, can also import .ps files directly, although, obviously, each in its own way. To the best of my knowledge, Acrobat, the PDF editor, cannot, but this may not be entirely accurate; if it can, I don't know how to do it (I don't use Acrobat for much more than reading PDFs).
