Last night the company Apple has released a new model of MacBook pro that has Retina Display, but it's almost as thin as the line of MacBook Airs. The device is almost as heavy as the Air, and their specifications are: Height: 0.71 inches (1.8 cm), Width: 14.13 inches (35.89 cm), Depth: 9.73 inches (24.71 cm), Weight: 4.46 pounds (2.02 kg)2in the case of the new MacBook Pro Retina Display, and Height: 0.11-0.68 inch (0.3-1.7 cm), Width: 12.8 inches (32.5 cm), Depth: 8.94 inches (22.7 cm), Weight: 2.96 pound (1.35 kg)2 in the case of the MacBook Air.

Note that the differences between the two products are minor, Apple managed to substantially reduce the size of the MacBook Pro to make it as portable as the MacBook Air, but the starting price of $2200 I think will make many people hesitate for now a purchase. And for the changes to be complete, Apple has implemented new MagSafe connectors in the new MacBook Pros that you have presented below. Having said that, below you have a comparison between MacBook Air and MacBook Pro Retina Display.
