XPS -> PDF

didn't came across such a product which is already finished yet, but maybe you have a look at "GhostXPS" from Artifex -> http://raph.levien.com/XPS%20only.pdf

however there doesn't exist a beta/release yet, as they're still working on - just contact them for more informations.. but maybe it's helpful anyway?

Conversion of XPS into PDF can easily be done with Adobe Acrobat Pro 8.0. And it works. The other day I downloaded the Microsoft Windows Vista Product Guide as XPS, and the conversion in Acrobat worked well. Don't expect files to get as small as if you saved them as XPS in the first place. I have tried to save smaller files as XPS and PDF and if you save a 2-page document with a couple of images in it, it seems that the sizes of the two documents will be appr. the same.

Yes, you don't even see the XPS files in the right way on a Mac, do you. We'll have to wait and see, if there'll be an XPS viewer for the Mac. Personally I doubt that, – and who should develop it?
Adobe is working on the Mars project, which is "an XML friendly implementation of PDF"
– look for more info at their site http://labs.adobe.com. If you wanna play, you can convert the file suffixes on XPS and Mars files to .zip and unzip them to see, what's inside.

It will be exciting to see, what happens, when the office people find out, they can print InDesign, Photoshop and more from Vista with XPS – or with PDF. Will they be confused? Will they stay with PDF files? Or will they be curious to try XPS files with one of the many printers, that will be able to print them?
