Asus revamped their entire lines of Zenbook (all-round thin-and-lights), Zenbook S (ultraportables) and Zenbook Flip (convertibles) laptops for the second part of 2018 and first half of 2019, and these are not just some minor updates.
The updated models are thinner, lighter and more compact than before, with tiny bezels around the display and especially tiny chins, as well as screen-to-body ratios over 90%.
