In 2006, 95% of Fortune's 100 are using PGP and 75% are in Fortune's Global 100. With Seahorse now being accepted in Gnome 2.18, I see that it will wound Microsoft badly. While Microsoft doesn't have PGP encryption applications of their own, PGP in Linux and Gnome is much easier to setup with Seahorse than ever before. This is one of the most important "killer apps" Linux and Gnome have, with companies all over the world have a great interest in PGP cryptography. Gnome's Groupware Suite, Evolution has long been using PGP cryptography operations, and now with Seahorse, it will "just works" pretty well, out-of-the-box. With Seahorse's integration with the Gnome Desktop, PGP cryptographic operations will now work from Text editors, Web Browsers to Nautilus File Manager. Seahorse in Gnome 2.18, I can say this is "really something!" Joel -- Stay away from Piracy, use Open Source.
