Revolutionary. One device designed for all jobs. Browsing, presentations, typing, mobility and working with a partner. The simple idea of installing a dual-TFT on the front and rear is to revolutionize using a Windows PC.

We’re used to seeing interesting designs when it comes to Windows 8 tablets and convertibles, but the Taichi takes the cake for originality.We’re not sold on the idea of twin displays and it’s obviously come at the cost of other components. If you can find a good reason to use both screens, there’s nothing else quite like the Taichi, although it feels more of a proof of concept than a usable solution.

There's little arguing the fact that the Taichi is a well-built premium laptop. And both of its screens are of excellent quality. But like pretty much every hybrid or convertible we've seen so far, its split personality results in a compromised experience on both sides. As a tablet, the Taichi is powerful and responsive, but it's also about twice as heavy as most similarly sized dedicated tablets. And battery life is also pretty short by tablet standards.

Windows 8 opened up new possibilities for mobile computing and the Asus Taichi 21 takes advantage of this. It has dual 11.6-inch 1080p displays where the second on the back of the primary display acts as a tablet when closed. Both of the displays look really good but the battery life is short. Asus really tried to keep the Taichi 21 light and compact and they certainly succeeded. It measures 12.1 x 7.8 x 0.7-inches (wdh) and weighs just shy of 3-pounds. The design is also eye-pleasing with an aluminum keyboard deck, sides and bottom with tapering edges to finish it off. Our only design question was why Asus put such a thick bezel around the primary display.

Overall, the Asus Taichi handled the Windows 8 OS very well, with very little lag when swiping between live tiles, and programs popped up almost as soon as we selected them. However, after installing a number of applications and storing a sufficient amount of data, we can imagine that it could slow down a bit.

The Asus Taichi stands up as a supremely desirable piece of consumer tech that acts as a sterling showcase for Microsoft's Windows 8 operating system. Both power and usability are first class, and the design - as we've come to expect from Asus - really is head-turning. The Asus Taichi works better as a laptop than a tablet, but it's one of the best examples we've yet seen of marrying the two form factors together.

The Taichi’s screen-on-screen action could be exactly what some people want – be they business types, show-offs or just wildly popular Ultrabook users who never get any peace from their adoring fans. It is a touch too unwieldy to use as a touchscreen tablet to justify that £1200 price tag, but it’s already available for less so you may not have to stretch right up to the RRP.

Many manufacturers are struggling to find the most natural meeting point between the tablet and the laptop, and Asus’ own Windows 8 range provides yet more evidence of this. With its VivoBooks marrying touchscreens to standard laptops, the forthcoming VivoTab range mimicking the separate tablet and keyboard dock concept of the Android-powered Transformer Pad, and the Taichi 21 ploughing its own dual-screened furrow, it seems even Asus isn’t confident enough to put all of its eggs in one basket. Give it a few years and a refined, lighter chassis married with more power-efficient CPUs and improved battery life could see this dual-screened form factor present a compelling hybrid. At present, though, Asus’ Taichi 21 feels like a bold, innovative concept that’s just a little too far ahead of its time.

With the introduction of Windows 8 and its touch-oriented interface and colorful tiles, many OEMs hastily launch laptops and tablets with touch screens to ride the wave of innovation. Some even introduce devices which can be used as laptops and tablets, e.g., the Sony Vaio Duo 11 with its sliding mechanism, the Dell XPS 12 with flippable display, and the Lenovo Ideapad Yoga which can open the screen to 360 degree. Among all these devices, the Asus Taichi 21 with its dual-screen stands out the most.

Basically, Asus took the already popular Zenbook prime design, put an additional touch-enabled screen on the lid, and called it Taichi. Thanks to its innovative design, the Taichi could attract many business customers. They can take notes in tablet mode during long meetings or present new products to potential customers in dual-screen mode. The idea behind this dual screen laptop is cool and a novelty for business users, and it works. The two high quality fullHD displays and the zenbook-like weight, built-quality and keyboard are worth mentioning here, as they make the Taichi a very attractive ultrabook.

The only two downsides of the Taichi are its somewhat short battery life compared to traditional ultrabook, which is average for touch-screen ultrabooks, and that the inner screen is not touch-enabled. The latter could be a deal breaker for many users. With the introduction of the Intel's 4th generation Core-i series, the battery life problem can surely be solved. If the Taichi concept is a little bit revised, it could be one of the most, if not the most useful, device for all scenario.

Intel HD Graphics 4000: Processor graphics card in the high end Ivy Bridge models. Offers a different clock speed in the different CPU models (ULV to desktop quad core) and therefore a different performance.

Non demanding games should be playable with these graphics cards.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.  

3517U: Fast Ivy-Bridge-based ULV-CPU in Q2 2012. Offers a core clock of 1.9 - 3.0 GHz and an HD 4000 GPU (350 - 1150 MHz). The TDP is rated at 17 W.» Further information can be found in our Comparison of Mobile Processsors.


This is a standard display format for tablet computers or small convertibles. You see more on the screen than on a smartphone but you can't use big resolutions well. On the other hand, mobility is not a problem.

Asus: ASUSTeK Computer Inc. is a major Taiwanese computer hardware manufacturer based in Taipei, founded in 1989. Under the Asus brand name, the company manufactures a wide range of products, including laptops, desktops, motherboards, graphics cards, monitors, smartphones and networking equipment, complete systems and PC components for end users.

Under the ROG (Republic of Gamers) brand name, ASUS manufactures gaming laptops known by gamers for their powerful specifications, dedicated graphics cards, high refresh rate displays and advanced cooling systems.

Beyond gaming, a wide range of notebooks are offered for different needs and budgets, from ultra-slim and lightweight ultrabooks to versatile 2-in-1 convertibles and budget-friendly options. In 2023, Asus had a 7% global market share of the PC market.

Customer satisfaction with ASUS notebooks concerns performance, the features, and the good price-performance ratio of ASUS notebooks. However, as with any brand, there are occasional reports of problems such as overheating, driver compatibility, or build quality issues.

71.63%: This rating is poor. More than three quarters of the models are rated better. That is rather not a purchase recommendation. Even if verbal ratings in this area do not sound that bad ("sufficient" or "satisfactory"), they are usually euphemisms that disguise a classification as a below-average laptop.
