The Asus ZenBook UX305 far more affordable than Most Premium Ultrabooks. Measuring just 0.5-inches thick and weighing 2.6 Pounds ( 1.17 kg ). This makes the Zenbook a tiny bit lighter, the machine is entirely made of alumunium. The interior deck is one solid piece of metal that features an anodized and slightly gritty finish, which is by no means abrasive and instead adds an extra bit of texture for your wrists to sit on. The laptops's underside also sports an anodized sheen, but it's a separate piece. So, this is not a completely seamless design.
The Asuzs UX305 has been given a radial pattern that's both attractive and conveniently draws your attention to the Asus logo in the center. Despite the small size of this Ultrabook, the trackpad is extremely roomy and extends over a third of the laptop's depth. Not only is it big, the trackpad is nigh frictionless. Better yet, clicks are tactile and audible whether you're pressing on the dedicated left and right buttons or pressing anywhere on the surface.
Similarly the keyboard does not feel cramped at all. It follows the standard keyboard format with a full length backspace and enter key. The keys are springy as well to round out this great typing experience. There's no denying the Asus ZenBook UX305 looks exactly like a MacBook Air. From the hinge, the bezel around the screen, the position of the trackpad to the recessed keyboard, you can easily see the similarities to the MacBook Air.
One of the few original touches Asus has added to the design are its chamfered edges as opposed to the MacBook Air's razor sharp sides. Otherwise, the UX305 looks like the MacBook Air after it's gotten a nip-tuck job to make it marginally slimmer and lighter. Via : techradar
