Exactly. Adobe Reader alternatives exist, but how many users have ever heard of Sumatra or Foxit? Adobe Reader is bundled with just about every piece of optical-drive-installed software that has a pdf user guide, and that's a large majority.

Back on topic, this isn't a surprise. It's amazing how many Mac lovers don't understand the difference between safety and security. As this article says, Macs fail at security. They may be safer for awhile, but only because of the lack of malware for them. I'm actually surprised that Macs haven't been targeted more, since I generally think of most Mac users as:
1) Rich; a lot of money to be scammed out of them!
2) Less computer literate, since they want a computer that just works out of the box instead of customizing it themselves, like Windows and Linux (even more with the latter).
I understand those two characteristics don't describe every Mac user; I'm speaking of them as a group.
