Featuring a thin and lightweight design, the mid 2017 Apple 13.3" MacBook Air features a unibody aluminum enclosure that weighs less than 3 pounds. At its thickest point, the computer is only 0.68" -- it tapers down to 0.11" at its thinnest. At 13.3" in size, the 16:10 display features a screen resolution of 1440 x 900. Scratch and dent products may have considerable cosmetic blemishes that do not affect performance. They are a great way to save money while still enjoying a rigorously tested device.
