Identification ¶ 

The first generation of MacBook Airs (models A1237 and A1304) is easily distinguished from the second generation (models A1370 and A1369) by a few exterior differences. On the first generation, there was a port cover on the right side of the laptop, whereas the second generation leaves all connections uncovered. In addition, the power button for the earlier models was part of the unibody case, but is included as a button on the keyboard in the second generation. The easiest way to tell the different models apart is to look on the underside of the laptop for the model number, which is printed on the case.
