Asus Zenbook UX21 Ultrabook, The New Thin

30 thumbs up
We're fortunate enough to get hands-on time with some pretty sexy hardware here at HH and we're not going to make any apologies for using the "s word" as it relates to this hot new notebook from Asus. Though some industry pundits might take issue with us describing this machine as "sexy," you'd have to agree this 12-inch slice of aluminum and cutting-edge technology is pretty damn sleek and pretty.

The Asus Zenbook UX21E is a new ultra-slim notebook by Asus, that fits into the new "Ultrabook" class of machines, to use a term coined by Intel. The Zenbook UX21E is an incredible 3mm thick at the front and 9mm at the rear and has spun metal and hairline aluminum for a strikingly sleek appearance. It's also built with Intel's new low-power Sandy Bridge Core i7 2677M mobile dual-core processor, 4GB of DDR3-1333 memory, a 128GB SATA 3 SSD and an 11.6-inch LCD with a native resolution of 1366x768. 

Here's a quick-take demo of the product in action, but be sure to journey on through the pages ahead for our detailed review with all the analysis and our usual benchmark gauntlet.

Intel's QS67 Express chipset offers a power-optimized version of the Sandy Bridge 2nd generation Core mobile platform solutions that have been shipping in the market for some time.  Specifically, the chipset supports things like Intel's RST (Rapid Storage Technology) with SATA 6Gb/s and 3Gb/s support, as well as eSATA (though eSATA is not available on the UX21).  The chipset also doesn't support USB 3.0 technology natively, but Asus offers one port of SS USB 3.0 connectivity via a discrete controller. Other notables with the UX21 are Bluetooth v4.0 for high speed connectivity up to 24Mbit/s with low energy protocol support and the machine's 128GB SSD (other models ship with larger and smaller capacities). This SSD is a 6Gbps "SATA 3" drive, that as you'll see shortly, offers impressive performance.



Asus bundles a nice kit with the UX21E, that includes a nylon and leather carrying case, minimalistic literature pack, a tiny AC adapter that helps you appreciate just how little power this baby draws and a pair of external dongles for wired Gigabit Ethernet and VGA connectivity.

It would be PERFECT if it had a backlit keyboard.... *sigh*

Could you guys review the Toshiba U300 ultrabook? It has a backlit keyboard :-D

Put in a hot graphics card and then it would be perfect.

Ultrabooks are not intended as a gaming platform, specification even excludes discrete graphics, though with the Ivy Bridge update the GMA should get about 30% performance boost along with the 20-30% CPU performance boost.

We should also see more power saving technology like Self Refreshing screens. So the GPU only wakes when screen content actually changes instead of constantly generating the same image over and over, among other power saving optimizations Intel will be introducing with 22nm chip production. Combined with the power savings from going 22nm, should boost the run times to more acceptable ranges. Not to mention lower system cost and that should start making Ultrabooks more appealing.

More traditional laptops will of course still be available and AMD will likely start offering their own version of Ultrabooks, they just can't call them Ultrabooks, sometime during 2012 when they start pushing their own 28nm ULV solutions.

Yeah, what JDiaz said. :-D

I have to agree. I mean these aren't supposed to be gaming machines, they're supposed to be general purpose laptops that are marginally powerful and have a slim form factor. I can see people using this to write documents, watch movies, and generally look stylish and the charts in the review shows that; it's hella powerful for what it is.

Also I love your ideas on power saving technology, you should give those ideas to all the major tech companies stat! The self-refreshing screen is something I would love to see that on a laptop in the near future.

Really it depends on what the main usage aim is for the machine. The main aim for these is mobility and for that this one looks about perfect.

I just wish Asus also like Dell would step up their game on the LCD panel used in these machines.

A good screen makes all the difference.

$1000 for barely mediocre performance :/ Size and style really costs. I don't see myself recommending this to anyone who isn't bathing in money.

Schmich, not sure which review you read but it must not have been ours. This machine offered way better than mediocre performance. In fact, it offered surprisingly good performance for its form-factor especially.

I liked the video, and I like the Zenbook too.

If I had the cash, I would buy it. Smile

It really DOES look great, and the performance is completely acceptable too.
