Although we would never accuse the Air of being bulky, we were surprised that Apple didn't make this iteration thinner than the previous model.

Accompanying the audio jack on the left side of the MacBook are the new MagSafe 2 connector and the first of two USB 3.0 ports.

On the opposite side, we find an SD card reader, the second USB 3.0 port, and—of course—Apple and Intel's brainchild: the Thunderbolt I/O.

MagSafe 2 is a luxury reserved (so far) for the new MacBook Air and the Retina display-equipped MacBook Pro.

As you can see, the new MagSafe 2 connector (bottom) is much thinner and wider than its predecessor. This is pretty significant, because the thickness of Apple's devices seems to be limited only by the size of their ports.

Apple never stops tweaking the details; they moved the symbols from the <a href="/Teardown/MacBook+Air+13-Inch+Mid+2011+Teardown/6130/1#s26654">rear side of the ports</a> to the front. If you're in a pinch and have to differentiate a Mid 2012 MacBook Air from a Mid 2011 model, just look at what side of the ports the symbols are on.

We'll go ahead and answer the question before it's asked: yes, you can swap 2011 and 2012 batteries. We're not really sure why you would, though, considering they are exactly the same.
