To conclude, the laptops come loaded with pretty interesting specifications. The ZenBook Pro 15 gives a stiff competition to MacBook Pro 15, though it features the similarly-inspired Touch Bar in select MacBook Pro models. The ZenBook S and ZenBook 13 are the ones that will face a stiff competition from the brands like Lenovo, HP, Acer and Dell.

Model: I think it is fair to say that if MSI is kind of the best in the gaming laptops (as there are lots of other good competitors), Asus is kind of the best in the ultrabook segment (need to consider Dell XPS, Lenovo Thinkpad models as well).
So, the Zenbook series is what I have in front of me. Specifically, the UX391. Why do I have it today? A few reasons. First, weight. It only weighs 1.1 Kg. Can you believe it? Think about the mobility. While carrying whether you have a notebook sleeve or keep it in your backpack, you would not even notice it is there. Secondly, the Intel 8th Gen. i7 CPU. Oh my. Third, 16 GB of RAM. What else can be there? Oh, I know. A touch screen, 4K resolution, Asus Pen, USB dock, Thunderbolt 3 and the list goes on. Any disadvantages? Well, I can only think of DDR3 2133 MHz RAM. That's a bit disappointing, but I have not seen a model from Asus that has utilized DDR4 RAM in this segment. I change my words, it is really disappointing.
Apart from that, the reason why I picked this model is because of its potential. It literally targets people that are looking for mobility. But do you need the touch screen when the design is not convertible? Flipbook S series has models with specific configuration and they have 360 degree hinges, which makes more sense with touch screen. For me I would have omitted the touchscreen and go for another SKU with a regular screen.
As someone who does lots of typing, doing development on the side, opening tons of software at the same time, this beauty is a beast. I do not feel the need to talk about keyboard, quality of the case etc. They are all top notch.
Here is the thing, beauty comes with a cost, in the literal meaning. UX391 is not cheap and not sure if it is for everyone. If mobility is your thing and you do not mind extra 150 grams or so you have the option to go for Dell XPS 13 models and if you add another 250 grams to that there you have HP's Elitebook 840 G5.
When there are other options to pick, it becomes harder to make a decision. If the money is not a problem, Asus and Dell are the picks to go. If your budget is a bit tight, then you can go for HP. Even with Dell and Asus, I am not sure if 4K is really necessary. It is better to find the models first and try from first hand before making a purchase online.
Hands-on article by Ümit Yılmaz GüneşIntel UHD Graphics 620: Integrated GPU (GT2, 24 EUs) found on some Kaby-Lake-Refresh CPU models (15 W ULV series). Technically identical to the previous Kaby-Lake GPU called HD Graphics 620. Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards. » Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.
Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.
8550U: Kaby-Lake-Refresh based low power quad-core processor. The four cores are clocked between 1.8 and 4 GHz (Turbo Boost) and support HyperThreading. The integrated GPU is clocked between 300 and 1,150 MHz. The SoC is manufactured in a 14nm+ FinFET process.» Further information can be found in our Comparison of Mobile Processsors.
Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.
Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.» To find out how fine a display is, see our DPI List.
This weight is typical for big tablets, small subnotebooks, ultrabooks and convertibles with a 10-11 inch display-diagonal.
