With the recent announced UX21 and UX31 Ultrabooks, provided by the Taiwanese manufacturer Asus and marketed under the self-created term Zenbook, the already existing UX series moves back to the foreground. In 2009 Asus showed the slim notebook UX50V with energy efficient hardware and a 15-inch display. Today, three years after the first device of this series Asus presents two devices in the Ultrabook-class with 11.6 - and 13.3-inch display. The category Ultrabook itself was launched by Intel to the fire up the market of the top dog Apple with its MacBook Air 11 and MacBook Air 13.
Significant milestones for this project are a sleek design, fast and energy-saving hardware as well as a decent battery lifetime. Asus uses a alloy-chassis, a solid state drive and a lithium-polymer battery, which is integrated. In the first reviews for the two new devices the available ports, the bright screen and the minimalistic background noises in idle-usage models are highlighted. Disadvantages are the reflective surface of the display and the missing option to expand the integrated hardware.
Asus offers the Zenbook UX21 (11.6 inches) and the UX31 with the larger 13.3-inch screen from 999 € (MSRP) upwards. In regard to other devices you’ll see that Asus only sell premium devices at the moment. Acer offers the Aspire S3 Ultrabook already from 799 € (MSRP) upwards. But in comparison the devices from Asus get a better result in the most reviews out there.Intel HD Graphics 3000: Integrated graphics card in the Intel Sandy Bridge processors (Core ix-2xxx).
