Yet another Vietnamese leak today has revealed Apple's next MacBook update early. The plastic model will bump up to most of the specs of the 13-inch MacBook Pro, including its 2.4GHz Core 2 Duo, 250GB hard drive and GeForce 320M video, but as always will still have conscious limits to drive some buyers to the more expensive model. It should still carry 2GB of RAM and use a 7-hour battery compared to 10 for the aluminum MacBook Pro.
