Just couldn't take Entourage any longer because of the spam and I switched over to Mail, which comes with the Mac OS. Still have some saved mail in the Entourage folder structures, so I'll need to keep the dinosaur around for a bit and migrate what I need when I need it, but I'm so happy with the different right now.
Address Book looks OK as well. Weird having it separate from the actual mail application, but its versatility looks promising.
I'm still a Word guy, though, when it comes to writing. Change is glacial, but it's still change.
