The MacBook Air and Samsung Series 9 have proven that you needn't settle for something barely more powerful than a calculator if you want an ultra-portable laptop. Now Asus wants a slice of the pie, with the UX21.
Like the Air, the UX21 will be available in an 11-inch version and have a ridiculously thin chassis. The UX21 narrows down to a minuscule 3mm at its thinnest end, as does the Air. The two laptops are also wrapped in a sturdy aluminium case, although the Asus model is noticeably shinier.
The Samsung Series 9 is also beautifully thin. Made from plastic and a metal called duralumin, it's slightly more susceptible to knocks and bumps than the unibody UX21 and Air.
The UX21's isolated keyboard has aluminium keys that look a dream to type on. Coupled with the large, glass trackpad, this machine looks as sleek and sexy as an otter in a negligée, whether it's open or closed.
Asus has equipped the UX21 with two separate buttons on the trackpad, rather than plump for a clickable pad, as you'll find on the Air and the Series 9. It's not a massive issue, but you can make a trackpad much bigger if you dispense with separate buttons.
