Superbly light, 1kg, this MacBook Air is a small wonder. I hesitated on size but open applications screen layout functions makes quite bearable screen. At the office I connect an external display, I recently changed to a screen mac ... The experience is just great. Two branches and it is set, the charger remains in the bag! All accessories are connected to the screen, and when I go I do not have to unplug everything. This solid computer is powerful and fast, nothing to say.
