The system includes several fiber optic channels to ensure that the illumination is distributed evenly.

The teardown of course also reveals the new keyboard backlight cable for evenly illuminating the computer's keyboard in dark conditions. As we briefly touched on in our 'notes of interest' article yesterday, Bluetooth 4.0 is supported on both the new MacBook Air and Mac mini and offers lower power, decreased latency, and greater security. A review of the new MacBook Air's wireless card shows two chips from Broadcom: a BCM4322 Wi-Fi chip and a BCM20702 Bluetooth 4.0 chip. This is not the case, however, with Apple continuing to use a separate, pluggable board for the solid-state drive. A report in the weeks leading up to the machine's debut had claimed that Apple might be shifting to new Toggle DDR 2.0 flash memory, which would be soldered directly onto the motherboard.

Apple is continuing to use a modular design for the MacBook Air's solid-state storage, meaning that it can be replaced or upgraded if necessary, although it is not officially supported as a user-replaceable component by Apple. Teardown and repair firm iFixit is well underway on a teardown of the new 13-inch MacBook Air, and while most of the computer's internals are nearly identical to that of its predecessor, a few items of note have been discovered.
