The ZenBook Flip S is a premium convertible, which is reflected by the chassis design. The combination of dark surfaces (Jade Black) with red copper accents leaves a very sophisticated impression. There are also concentric circles on the lid, which is familiar from previous ZenBooks. However, the smooth surfaces quickly attract fingerprints.
The case is made of an aluminum alloy and the overall stability is very good. The keyboard deck is slightly lowered, which allows more key travel. This does not impact the stability, because neither concentrated pressure, nor twisting attempts can create creaking noises. The lid is also very sturdy, and the additional glass layer from the touchscreen certainly helps as well.
Asus uses a so called ErgoLift hinge design, which means the rear of the base unit is slightly lifted when you open the lid. This results in a slightly more comfortable typing position and also improves the air flow underneath the device at the same time. The Flip S is a convertible, so you can flip the display back and use it as a tablet, for example.
The bezels at the sides are very narrow at 3.9 mm, but the bottom bezel in particular is a thick black bar. A 16:10 panel would have fitted here as well.
