Don't forget to look in the refurb section of the store. Its labeled "Special Deals". You can save a some decent loot on a refurb or slightly older model. They are re-certified so you get the standard warranty and you can buy Apple care for them. I've gotten these for my jobs in the past. All worked 100%. Or find a student who doesn't want to use their educational discount. It actually works out to about the same as buying a refurb.
I love my MacBook and all my other dumb macs.
