>The reality: As it is, however, hackers do not use the Hacker Equation -- they rather gauge their potential impact based solely on the popularity of an target software, and hence Mac and Linux and OpenOffice etc. have been largely spared too many serious hacking attempts.

No, I didn't keep the link.
