Since going over to OSX, I've become more Apple aware and would like to get away from MS products wherever there are Apple replacements. This is the case with Entourage and Mail. I successfully exported and imported addresses from Entourage to Address Book. I like the integration between Address Book and Mail. I find Mail has a very simplified interface- that's okay. But I find this- when I open up Addresses in Mail and click "To", nothing happens. Is there any known issues where Mail doesn't work in some area? I'm willing to move entirely over to Mail if it works. Does anyone have any experience using Mail as a default email app? What are the limitations with Mail compared to Entourage? I was an OE user in OS9, but, since it's not native X, it's out.
