When Apple introduced the new 13" Aluminum Unibody Macbook Pro many people decided that their 13" aluminum Macbook just wasn't good enough anymore.
Fortunately for the budget conscience this left a flood of cheap Macbooks on the market.
Whenever Apple introduces a new line up it is the perfect opportunity for those looking to purchase a computer without paying full retail to capitalize. Sometimes you can even find a brand new previous version Macbook at your local electronics store at a discounted price but you have to act quick as they go quickly.
A good play to find previous version cheap Macbooks is on eBay. Those people selling their previous versions Macbook are anxious and willing to sell quickly and at a much discounted price.
