ASUS says the Zenbook S 13 OLED is the world's lightest laptop with a 13.3-inch OLED screen with 2.8K resolution. I tend to take their word for it, but it's not like a few grams or even dozens of grams really make a difference when choosing one notebook over another. More important are many other features, and the Zenbook S 13 OLED manages to come with a compelling package at a fair price.
