Asus Zenbook Prime UX31A Video Review

Last year's Asus Zenbook UX31E Ultrabook got top honors with reviewers and shoppers alike. It was a sleek, sexy metal notebook with higher than average resolution and strong performance. It was also one of the first Ultrabooks to hit the market, and that gave it an obvious advantage. Since then many competitors have released Ultrabooks that addressed some of the Zenbook's shortcomings. Asus is an aggressive company that listens to customers and they've not only improved on our complaints, but added a killer feature: a 1080p IPS display.

The Zenbook Prime UX31A is a 13.3" Ultrabook running on third generation Intel Ivy Bridge ULV CPUs. Asus offers it with 1.7GHz Core i5 and 1.9GHz i7 dual core CPUs, Intel HD 4000 graphics, 4 gigs of RAM soldered to the motherboard and 128 or 256 gig SSDs. We take a look at the Core i5 with the 128 gig SSD for this review, which scored an impressive 12,700 on PCMark Vantage. All Prime models have a 1080p IPS display, SSD and backlit keyboard. Yes, even the Zenbook Prime UX21A 11.6" model has a 1080p display!

The 2.86 pound UX31A Zenbook Prime looks much like the first gen Zenbook, and that's a good thing since that machine was stunning looking and well made. The casing is metal and rigid. The combo of a dark swirl lid and a brushed stainless steel hinge barrel and bottom look great. The laptop looks and feels like a high quality piece of tech that holds its own against the MacBook Air. Like the Air, it tapers and is 3mm thin at the front and 9mm at the rear.

The Zenbook Prime has two USB 3.0 ports (one charging), micro HDMI, mini VGA, 3.5mm audio and an SD card slot. Like the last Zenbook, Asus includes a USB Ethernet adapter and VGA adapter in the box and a brown ballistic nylon slip case.

Asus has greatly improved the keyboard with much better tactile feel and key travel. It's backlit and you can control backlight level via Fn keys or let the ambient light sensor handle it for you. I honestly came to hate the original Zenbook keyboard, but so far find the Zenbook Prime's keyboard to be enjoyable. The trackpad is improved as well, with more reliable tracking and multi-touch behavior, but palm rejection is weak.

The Zenbook Prime impresses before you open the lid thanks to the elegant industrial design and sturdy feel. Open it up and the 1920 x 1080 IPS display seals the deal. The matte panel is simply gorgeous: very bright, lovely balanced colors and high contrast. Text is sharp and black levels are excellent. Asus didn't skimp here. The 350 nit brightness panel is brighter than most notebooks on the market (disable the ambient light sensor if you really want to blast your retinas). The display will likely set the Zenbook Prime ahead of the competition for some time.

The Asus Zenbook Prime UX31A starts at $1,099 for the Core i5 with 128 gig SSD.

Re: Asus Zenbook Prime UX31A Video Review

Thanks Lisa. Your reviews are great!

Ihave been waiting for your review of the ux31a and I have also looked at your review of the Sony Z3 and I am trying to decide between the two.

I use my laptop all day w/ RDP to a desktop over wireless - and would use it for misc other office apps and movie watching during travel. The most important things to me are (1) 1080p resolution, (2) Good keyboard & touchpad setup for extended use, (3) lightweight - both for around the office & for travel w/charger (4) extended battery life (for the Sony I would get the battery slice which does not have an equivalent for the Asus) (5) TPM chip and Windows Professional (so I have to get one of the higher end Asus models and the model I would get is the Ux31a-XB72).

I am very torn between these two and from your reviews, both laptops are great. The additional cost of the Sony is not a big factor. From your descriptions of product - I would love to get your input on this. What would you recommend? Which would you like better for your daily machine? And is it a case where I would probably be happy with either one?

Please help - I would appreciate any input you could give

Re: Asus Zenbook Prime UX31A Video Review

I know I'be be extremely happy with either one!

I like the wider viewing angles on the Zenbook Prime and can live with 72 percent color gamut vs. 96 percent on the Sony Vaio Z. But either way, you're looking at top notch displays.

For what you're doing, you don't need all the power of the Z, and the UX31A could handle things just fine.

The Sony Vaio Z trackpad is tiny, though it works well. I did find my finger wandering off because it's so small. The UX31A's trackpad is larger but I like the Sony's responsiveness better. However: uninstalled Asus Virtual Touch software and the trackpad works much, much better!

I'd give the edge to the Sony keyboard, but the Asus is quite good too.

No extended battery for the Asus, as you noted. The Sony Vaio Z with sheet battery will run 2x longer than the Zenbook Prime.
