Your wife won't have a thing to complain about. I'm using Entourage but honestly if I had my time over again, I'd just stick with the basic Mail program. I mean, email is email, right?
What REALLY sold me on the Mac was when I bought a MacBook a couple of months ago, plugged it in, opened the lid and it looked around and said aha! I sense a wireless network! I clicked on Safari and bugger me if it wasn't connected straight to the internet!
I'm still a novice myself, so any problems you post will probably be of interest to me and other neophytes. Don't hesitate. JB may not be what it used to be but this place is a hidden gem!
