Some interesting security features in the newest Apple OS X upgrade - encryption and secure deletion. Very cool. And I like this quote from the NYTimes review:
Finally, surely there's value in using an operating system that, well, isn't Windows. Mac OS X isn't just free of viruses; it's also free from copy protection, "activation" (a Windows XP feature that transmits information about your PC back to Microsoft), and pop-up messages that nag you to sign up for some Microsoft database or clean up your icons. When you use Mac OS X, you feel like it's yours; when you use Windows, you feel as though you're using someone else's toys, and Mrs. Microsoft keeps peeking in on you.
The FBI stops by a middleschool to check on a student writing a paper on bridges. But the really interesting bit here....
All of this leaves one question: How did the FBI stumble onto the information? Are there agents who spend their days monitoring millions of private messages?
Interesting post on Internet threat models.
