Initial touch of PC case looks like in Zenbook notebooks. Taichi Ultrabook UX21 has a brushed aluminum metal body. When you take Taichi in hand you will be surprised by its weight which is slightly more than 1 kilogram.

Top cover is coated with glass around the screen and has a metal frame with a thickness of about 3 mm, which highlights the display. Since this outer surface is shiny, it’s  easy to notice prints and wallowing. About the internal display has a matt black plastic frame on which the camera is located at the top of the Asus logo on the lower middle part.

As with all Ultrabooks, external interface is small. The power button is located on the right side. This prevents inadvertently pressing it. Next to it is the indicator that display mode in which the laptop currently is and follows Micro HDMI version 1.4, USB 3.0 and the charger.

The left side is reserved for 3.5mm-enabled combined (headphone / microphone) connector, USB 3.0 with support for USB charger, miniVGA, large buttons for volume control and switch on / off the external display. The sound quality is confirmed by the “Audio By Bang & Olutsen ICEpower” as well as in the rest of the ultrabooks of this class.

Something that is more important than the design and physical appearance, is of course the functionality of the laptop. As already mentioned this hybrid notebook has two displays. It’s external display that is touch screen is a 11.6-inch with a resolution of 1920 × 1080 pixels, and it is pleasant to touch without any difficulties in everyday use.

Thanks to the high-resolution, image display is rich and clear and pixels are not visible. Perfectly complements the IPS matrix which has a large viewing angle.

On the lower part is the “Start” button which serves to return to the homepage. Next to him is a 5 MP camera with sensor autofocus.

The screen is coated with Corning Fit Glass and supports up to 10 simultaneous touches. Using TaiChi 21 as tablet leave only pleasant moments, not taking into account the rapid mess of glass hampered work on the 11.6-inch touch screen with a resolution of 1080p. Is too low for use with a finger, but the problem is solved with the electronic pen that comes with the laptop.

Shifting from a tablet into a laptop without difficulty, the lid can be opened with one finger, and the screen automatically. The internal display is also a Full HD 1920 × 1080 pixels, but it is not touch screen with a diagonal of 11.6 inches, and IPS matte matrix. Color image is clean and clear. High resolution on a small screen, and here come to the fore as with external display, letters are too small and hardly visible to the daily work. Apart from this remark everything else is made and works great.
