NEW APPLE MacBook AIR

The original MacBook Air was very light on connectivity. It had an angled MagSafe power connector but that was it for visible ports. The right side of the machine was home to three hidden connectors: mini DisplayPort, USB and line out.

The new design forgoes the rounded nature of its predecessor and introduces more angular surfaces toward the rear of the machine. Connectors like flat surfaces so Apple outfitted the new MacBook Air with a pair of USB ports (one on each side) in addition to the MagSafe connector, miniDP out and line out. Everything is fully accessible from the start, nothing is hidden behind any secret panels.

Next to the headset jack on the left side is the integrated microphone. Apple states it is an omnidirectional mic, but its placement is curious given Apple typically places its mics at the top of the screen bezel. The microphone’s left leaning location didn’t negatively impact audio performance in our tests. As long as you’re not sitting to the right of a horribly noisy person/animal/box you should be good to go.
There are of course now two MacBook Airs that make up the family: an 11.6-inch model and a 13.3-inch model. The two have identical port layouts however the 13-inch MacBook Air gets an integrated SD card reader like its Pro siblings.

There’s a 0.6 pound difference between the two models and associated difference in dimensions:
