The Asus UX31 ultrabook has a 13.3-inch display with a very high 1600 x 900 pixel resolution (higher than many 15.4-inch laptops), and is remarkably thin at just 0.67-inches, the same as the smaller 11.6-inch UX21. The weight is also very light at just 1.1 kg (2.4 lbs), which is 250g (0.56lbs) lighter that the current 13-inch MacBook Air. So the UX31 really is lighter than Air.
The base configuration of the UX31 sees it come with an Intel Core i7-2637M (1.7 GHz) processor and a 128 GB SSD. Battery life is quoted at 7 hours.
Other specifications include an SD card slot, 2x USB ports, Mini-HDMI and Mini-DisplayPort outputs.
NetbookNews took a look at the Asus UX31 and were very impressed by it. They “loved the build quality”, saying it felt extremely solid and well built., and had a responsive glass trackpad.
