Apple has very recently released an updated to their white Macbooks. They have had a bump in processor speed, along with an upgrade to the Nvidia 320M seen in the 13 inch Macbook Pros. With this comes the brilliant 10 hour battery life of the 13 inchers.
With this update apple has enabled the ability for the Mini DisplayPort to transfer audio as well as video. Good news for those who want to plug it into a TV with an HDMI adapter, and who wouldn’t since it can play HD movies silky smooth.
