Review Asus Zenbook UX21E Ultrabook

 

Perfection. The power version of the Zenbook, with a Core i7, is as handy as a netbook but faster than most multimedia machines. How is this possible with a build height of 17 millimeters? The lightning-fast ADATA SSD sets the standard higher than ever.

Low weight and slim case, Stiff & high quality aluminum case, Good input devices, Very good application performance, Extremely fast SSD, Very bright screen, Unequivocally solid aluminum body. We gladly accept the few grams more compared to the MacBook Air

Few interfaces, Reflective screen, Poor colors, viewing angles, RAM & battery built-in permanently, Short battery life of less than four hours, Very loud during load, A battery life of at least five hours and wide viewing angles

Asus Zenbook UX21E-DH52

 

A mix of ultrabook and ultraportable, the Asus Zenbook UX21E-DH52 is a formidable challenger to the 11-inch MacBook Air.

Marvelously thin and light. Bright screen. Nifty AC adapter. VGA and Ethernet dongles and case included

Stiff, non-backlit keyboard. Reflective screen. No memory-card slot. Lethal power button position

Asus Zenbook UX21E-DH52

 

The Asus Zenbook UX21E-DH52 has an 11.6-inch screen, an Intel Core i5 processor, and the same 4GB of RAM and 128GB solid-state drive as its bigger sibling. In terms of high performance in a trivially light package, it's a netbook's worst nightmare. But...

Asus ZenBook UX21E

 

It's not every day that we see a whole new category of notebook computers emerge. Nonetheless, here in late 2011, off we go headfirst into the "ultrabook" era.

Highly portable ; Strong and fast performance ; Gorgeous polished-aluminum case ; Superb audio system

No memory-card slots ; Keyboard a little shallow, and lacks backlighting ; Slightly less-than-vivid color reproduction

This sleek and modern-looking ultrabook is an impressive, MacBook Air-style thin wonder. It will make an excellent travel companion for anyone demanding power and extreme portability.

Asus Zenbook UX21 Ultrabook, The New Thin

 

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...

Gorgeous good looks ; Exceptional build quality ; Light as a 2.4lb feather ; Top-shelf ultra-low power components ; Solid battery life ; Great performance

No DVI or HDMI output ; No backlit keyboard ; Key cap travel is a bit shallow, takes getting use to

The Asus UX21E-DH71 surprised us more than once in our assortment of tests. The machine offered some of the best standard application and multimedia performance scores we've seen from an ultralight machine to date. The UX21's PCMark Vantage and PCMark...

Asus Zenbook UX21

 

While the Zenbook UX21 ultrabook does lack many of the higher-grade parts of others in the Asus Zenbook family, it is still an excellent ultrabook. You get an LED screen with a 16:9 resolution, an ultrathin design and an HDMI port so you can hook it up...

The UX21 is thin, sleek and can boot up from sleep mode in under three seconds

The keyboard isn't backlit, and the tracking on the keypad seems to be too sensitive

The track pad is frustrating, and the UX21 lacks a memory card reader, but it is simply one of the more beautiful utrabooks on the market.

Asus Zenbook UX21 review

 

One of the best 11-inch laptops - but can it justify its price?

Light and slim ; Sandy Bridge power ; Strong ; Carry case supplied ; Great battery life

Pricey for an 11-inch machine ; Small keyboard ; Limited connectivity ; Frustrating track pad

The Asus Zenbook UX21 is the first 11-inch ultrabook to hit the shelves, joining the likes of the Acer Aspire S3 and its bigger brother, the Asus Zenbook UX31.

Asus Zenbook UX21E review

 

The Asus Zenbook UX21E is a shiny example of the modern 11in ultraportable notebook.

We’re inclined to affirm that we do believe in love at first sight. But since that initial look was of the laptop that launched this copy, our heart does stay with the MacBook Air. Make no mistake though, the Asus UX21E Zenbook is the best copy of any...
