If you save your graphics out as PNG files (rgb 24bit), they work fine in Word on the PC side I hear.
This latest from an Applelust review article for Adobe Creative Studio:
There is also a new save command: Save for Microsoft Office. Save for Office essentially makes a portable network graphic (PNG) file for those poor souls limited to Office options on PC systems. I'm personally quite thankful for this addition - I've spent too much of my life on the phone talking clients off the ledge after they tried to toss an EPS file into any Office application. Microsoft Office applications simply do not understand CMYK colors, let alone Pantone Spot Colors. A nice little RGB PNG is just the ticket for these folks.
