Until a few months ago the term ‘Ultrabook’ didn’t exist. Referring to a  new category of Wintel powered ultrathin products designed to take  Apple’s Macbook Air head on, the first mentions of the name came at  Computex, a few days after ASUS unveiled its UX21 laptop.
  	At the ASUS launch in Taiwan we had a chance to get some glimpses of  the UX21 through the pack of camera wielding journalists that descended  upon it every time it was being displayed. On the hype scale it came  second to the Padfone tablet/smartphone hybrid, but it still impressed  us a lot (once we released it was running a Core i7 rather than an Atom  processor).

  	It was the UX concept that sparked the Ultrabook idea by Intel, which  is making special variants of its Sandy Bridge processors for the  laptops. Since then there have been rumours coming out of Taiwan that  there is some serious back and forth going on between Intel and laptop  manufacturers, largely over the cost of the components and the  subsequent ability to be price-competitive with the MacBook Air. The  latest reports  from Digitimes are that tier one manufacturers are getting a 20%  discount on processors and that’s it.
  	12 and 13in versions
  	To date most of the Ultrabook focus has been on the 12in UX21, but ASUS  has a second model with a 13in screen that will soon be in production.  Called the UX31, there are a handful of samples floating around the  globe, and we made a visit to ASUS’ Sydney offices to take a look at  this thin and light beauty before it finished its brief visit to  Australia.
 	After spending a few hours with this beauty our excitement levels are  high. While there are certainly compromises made to get high end  hardware into a small form factor, the end result is a razor thin laptop  with power that belies its size. Inside the 3mm-17mm wedge of unibody  aluminium sits a Core i7-2637M clocked at 1.7GHz (which is half the  speed of a desktop Core i7-2600). This is paired with 4GB of DDR3 and a  128GB Sandisk SSD. Shipping models will come with either Core i5 or Core  i7 CPUs, and SSD capacity will include 64GB, 128GB, and 256GB options.  The 1600 x 900 13in LED backlit screen is driven by the processor  graphics built into the CPUs, which has been key to getting everything  into the tiny chassis.
  	Also in this wedge sits a Lithium polymer battery, which we didn’t get a  chance to test. ASUS is claiming this will deliver 7 hours of battery  life. One other factor that helps eke the most out of this battery is a 2  second resume from sleep when the lid is opened. This enables a usage  model where the UX31 can be removed from a bag and re
 	The chassis itself is a unibody aluminium design, with a somewhat  striking circular polish pattern around the ASUS logo on the lid. Open  it up and there is a large scrabble-tile keyboard, suitable for even the  comically massive hands of this writer. The touchpad seemed quite  responsive and the aluminium surrounding it all was refreshingly  resilient to fingerprint smudges. Audio quality wasn’t up to the level  of some of the better engineered laptops out there, but it was  surprisingly good for something in such a sleek form factor.
  	We also nerded out a bit over the way ASUS has integrated the  ventilation slots into the screen hinge, making them relatively  unobtrusive. We did a bit of a manual check of the base for hot spots  and couldn’t find any telltale signs of where the CPU was – but we had  only been running light workloads and will revisit it with some more CPU  intensive benchmarks once review hardware becomes available.

omparisons to the Macbook Air  are inevitable, and despite our initial worries that one could do  little to differentiate a tiny wedge of aluminium, ASUS is playing to  the strengths of the Windows platform with the UX31. On the left hand  side (near the back, which is the only part thick enough to house ports) sits a USB 2 port, headphone jack and SD  card reader. On the right side sit the hole for the charger, a USB 3  port, Micro HDMI and Mini-Displayport slots. This is a perfect feature  set for such an on-the go product.
  	We should know soon exactly what the plans are for an Australian launch  of the UX31. It is definitely coming, but ASUS is ironing out specs,  prices and timing. Odds are that Acer will beat them to the punch, with a  local Ultrabook launch scheduled for early September, but given  everything we have seen to date of the UX31 and UX21, ASUS is setting a  very high bar for the competition.
ady to go near  instantly, which all plays into the convenience that Ultrabooks are  supposed to deliver.
