MacBook Air - Review - Structure - part 2

The pointer’s command (and not only) is trusted to the multi-touch trackpad. This system allows for a series of extra commands by touching the trackpad in a similar way to the iPhone. It is possible, for example, to zoom or spin documents simply using more than one finger at the same time, making intuitive and often natural gestures, that often result in a time saving as well.

The optical unit is missing, which was a needed choice in order to achieve such aesthetical results. On the front part, there is an infrared receiver for the Apple-Remote remote control (sold separately), while on the sides, hidden by a small cover, we can find the only physical ports present on this laptop: an USB port, a headphone jack and a mini-DVI to connect monitor or video-projectors.

There is no Ethernet port, but the latter is replaceable by using a specific adaptor (sold separately) that transforms the only USB port in an RJ-45. The MacBook Air features, however, all the necessary technologies in order to perform an “air connection”, whether on the Wi-Fi 802.11n connection or Bluetooth 2.1 with EDR.
