It will be interesting to see if you and get AppleCare+ or just AppleCare Protection Plan for a refurbished unit. Let me know what options you get if you decide to get AppleCare and it is within the first two months.
Edit: Nevermind, I just looked at the refurbishment process link and it specifically says it is for AppleCare Protection Plan only :/ not worth it unless you are looking to travel with the mac.
