Apple’s site has just been updated with the new MacBooks. A replacement to the iSight Camera is included, called FaceTime HD, and Thunderbolt ports are also featured. More to follow.
UPDATE: The new MacBooks maintain the design, weight and dimentions of the previous iteration, but include super-fast Sandy Bridge processors and the much-rumoured Thunderbolt port. We have a couple of these in the office, and all we can say is they are fast. Expect a review in iCreate at some point soon!
