Most here would advise you not to use PowerPoint but use a TeX based 
presentation package. You do know, of course, that "PowerPoint is Evil" 
(google this phrase to find out why). If, like me, you are sometimes 
required to use PowerPoint, I would suggest converting your pdf'd to 
png's. After much trial and error, I concluded that png import to 
PowerPoint looked the best under most circumstances and is compatible 
with those that want to open and edit the words (but not the png's) in 
Windows. GraphicConverter or ImageMagick (available through 
i-Installer) will do this for you. Alternatively, you could use 
KeyNote, which always looks good with pdf imports (when you can get 
away with it).
