Reviews for the Asus ZenBook S UX391U
The ZenBook S (UX391) is a particularly light 13.3-inch laptop from Asus. It tips the scale at just 1 kg, but the manufacturer says the performance is not affected. We review the rival for the XPS 13.

Archive.org versionIf you’re in the market for a traditional Windows laptop that won’t weigh you down, the ZenBook S is a solid choice. Despite its small size, it has enough power for most tasks. Battery life is a letdown, but the S is still a good option unless you need to be unplugged for a full workday at a time.

Archive.org versionThe Asus ZenBook S isn’t the world’s thinnest, most affordable or even a 100% uniquely designed laptop, but it still looks like the Ultrabook to treat yourself with right now.

There are hardly any tablets in this display size range anymore. For subnotebooks, on the other hand, it is the standard format.
The advantage of subnotebooks is that the entire laptop can be small and therefore easily portable. The smaller display also has the advantage of requiring less power, which further improves battery life and thus mobility. The disadvantage is that reading texts is more strenuous on the eyes. High resolutions are more likely to be found in standard laptops.
