  • Spectacular build quality
update 03/31: they should remove the numberpad functionality description on this item. I know it's optional on some models, but the one sold here in amazon does not come with this numberpad feature. it's supposed to be built-in the trackpad and there's a button you press to switch between the numpad and the trackpad just like the ux333/ux433 models, however there's only the fingerprint scanner for the model listed here in amazon. I wouldn't ding a star since overall value proposition is still great imo original review: when i first opened the box, you get 2 extra goodies- a carrying sleeve and an optical mouse! very useful and a nice freebie imo. booting up the unit was fast- well all ultrabooks now that comes with a pcie ssd and windows 10 boots up really quick now less than 10 secs. although checking out the spec sheet- m.2 ssd is only a pcie x2 lane not the x4. crystaldiskmark reveals a 1500+mb read and a paltry 600+mb write. its fine for its use just for daily computing needs and the occasional webrowsing and office work. also don't get confused with this one and that other zenbook 14 the ux433- that one comes with an IR windows hello (as opposed to this one's fingerprint only windows hello capability), a slightly bigger 50whr battery compared to this one's 47whr. battery life is ok for now, im averaging approx. 6hrs on my intended use- power mode set to better performance on the windows slider (not the better battery). I was hoping to get at least 8 hrs of battery life but maybe it's just the way i use my computer- brightness set to 50%. Further, the trackpad is windows precision- so its the best that you could get in a windows computer. tracking is good and smooth. Display quality is excellent- colors pop, viewing angles are wide since its IPS and i couldn't detect any light bleeding on the edges- quality control is very good. it gets fairly bright too. i just set mine to 50% most of the time in normal lighting condition. Keyboard tactility is par for the course- great travel distance and the keyboard deck doesn't flex thank god! attesting to the Military grade spec standard its suppose to be certified with. Overall this is a very decent, very beautiful ultrabook and i especially love the mix of materials and color choice- it looks classy, business and professional. also i got it on lightning deal here at amazon saving me 120$ from MSRP although the additional tax lessened the discount to 85$- but still one helluva bargain. I could buy a pair of shoes for that extra savings. Will be updating this review as i got to use it more frequently. All in all, a very good buy! ... show more

  • Elegant, powerful, and light
I bought this for my wife since her 8-year old Macbook Air has been getting old and feeling slow now. I didn't want to pay again more than $1000 for a laptop. All she needs is MSOffice and Chrome, it doesn't matter if it is MacOS or Windows. I wanted a laptop with comparable quality and good looks at a lower price. So in the end, ASUS Zenbook 14 looked like an option. The hardware is actually better than Macbook Air since Zenbook 14 has U series quad-core processor instead of dual-core Y-series processors used in latest gen Macbook Air. I have been using a Y-series dual-core Dell Latitude E7370 Ultrabook and I can tell that the quad-core U-series CPU is noticeably faster. However U-series CPUs require better cooling. My Dell E7370 does not even have a cooling fan and about 1/2 lbs lighter. I think the interesting LCD hinge design of Zenbook 14 actually helps with cooling (more than ergonomics as advertised) by elevating the air intake grill at the bottom for better air flow. When the processor is has work load, I can hear the fans of Zenbook 14. Screen is a very high quality LCD panel, it has accurate colors, good contrast, and brightness. The body looks very much like metal (although I think it is plastic) and there is no excessive flex; construction quality is strong and materials feel high quality. The installed Windows 10 came with McAfee security software which I have uninstalled at once together with some other minor unnecessary software like ASUS application store, LinkedIn, and a couple of games. I have reverted back to default Microsoft security software and I did not feel the need to reinstall Windows. I have updated the Intel graphics, WiFi, and Bluetooth software to the latest versions directly from Intel as well (installing graphics driver required uninstallation of the original). WiFi performance (Intel AC 9560) is pretty good with our TPLink A7 router. The SSD is an OEM Western Digital unit and performs great. Keyboard is backlit with three lighting levels plus it can be turned off. Actually, keyboard backlight was initially off and I had to figure out that the F7 key was controlling it. Oh and the sound! Zenbook 14 has a very good sound system. If there is nobody to disturb around, one can simply enjoy the music/video without the headphones. The battery life looks decent; it can easily last two full movies on battery or typing a document all day. The keyboard has good feeling with decent travel distance while typing. I would still prefer my Latitude 7370 but ... anyway. The trackpad has good sensitivity and response as well. Overall, I think 5 stars rating is well deserved. My wife is happy; not looking back at her old Macbook Air. I would have given 6 stars if the price was $100 lower. ... show more

  • I'm Disappointed in Asus
I've been a long time Zenbook fan and have owned two Zenbooks over the last several years. These older units were really nice for the day. They had a beautiful aluminum case and were super thin. Battery life was descent. The one thing that I always hated was the charging port. The connection was always lose and prone to falling out or being bumped and damaged. I had assumed that Asus would have fixed this issue. Well I was horrified to find out the same old crappy charging port was still being used. My last Zenbook had a backlit keyboard which was amazing when I was in a dark room and wanted to type. I was disappointed to find out that Asus chose not use back lighting on the keyboard. I asked before it was purchased and was told by one person, from the company, it did have it and another person said no. I figured I would wait and see. I went into the Microsoft store and put a similar Asus next to the Matebook pro. The Asus was dim in comparison and colors were not saturated. The screen lacked contrast and had glare. The Zenbook being sold here seemed to have the same screen but with a smaller bezel. The Matebook was so much better. However, for re-sale I knew the Asus was the way to go. I didn't use it for more than 5 minutes once I saw these deficiencies. Honestly, I think Asus is under a lot of pressure to get a Zenbook to market for under 1k. I got a flash sale and bought it for 738 with tax which is a good price. The Matebook is way more. In conclusion,not having a back lit keyboard and the charging port were deal breakers for me. ... show more
