You don't want opinions on this --what good are they? :-) You want facts.

Google "pdf malware" for plenty of empirical data. For instance:

Feb 22, 2009 ... Security companies are warning of a new Adobe flaw that could compromise a PC merely by opening a malicious PDF...

Nov 1, 2007 ... Malicious PDF files accounted for up to two thirds of infected email in three day spam campaign.

Jan 7, 2010 ... Adobe will patch a security flaw on January 12th, 2010. Until then, hackers are using this flaw to launch attacks and hijack computers

... and about 5 million more.

PDFs can contain executable code, and that means there are potential security vulnerabilities to exploit. I seem to be getting security-related Acrobat patches every week or two.

If you've got Acrobat or Reader on your system, I hope you have updating turned on. If you're using some other vendor's PDF tools, I hope you have confidence in that vendor.
