Notebookcheck's Top 10 Convertibles

Redaktion (translated by Martina Osztovits), 11/14/2014

November 2014 update. Here you will find the best convertibles reviewed by Notebookcheck in the last few months. Our list of top models is regularly updated, maintained and commented on and should assist in purchase decisions.

For the original German article, see here.

Convertibles, sometimes also called Two-In-One or Multimode-PCs, are not a recent invention. In the business sector, these hybrids of notebook and tablet have been known for a long time, but they eked out a niche existence until recently. With the advent of tablets, manufacturers rediscovered the potential advantages of such devices.

While the first convertibles were relatively heavy devices with severely limited mobility, current CPU and battery technology allows for slim and mobile devices with decent performance. So, they can handle nearly all everyday PC tasks and tablet mode enlarges their field of application. Windows 8 provides the necessary user interface with its tile surface and the known desktop environment for productive use.

Microsoft Surface Pro 3
Microsoft Surface Pro 3

1st

The Microsoft Surface Pro 3 follows the previous Pro models and tries to perfectly bridge the gap between notebook and tablet again. It is primarily up to the beholder how well this has been achieved.
In our first test of a US model, we found a robust and stylish magnesium case. Alike the predecessors', it includes a stand, which can be fixed into different positions. The Type Cover is optionally available for a steep $130, but it should not miss in productive use, although it cannot keep up with a good notebook keyboard. In contrast, an active pen is included.
While the display was throughout convincing in our test, thermal restrictions limit the performance under load. If demanding applications are usual, you'll also have to accept increased surface temperatures and a loud system noise. The subjective performance was still very good. The expected battery life is also good. 8-9 hours is to be expected during web browsing via Wi-Fi. Depending on the configuration, the price of this bundle is about $1000.

2nd

HP's EliteBook Revolve 810 G2 focuses on professional use and uses a familiar convertible solution with a central turn and tilt hinge. In our review, we liked the case, the input devices, and the matte display, although the screen real estate would profit from a higher resolution.
Depending on the configuration, the device also has performance reserves for complex office applications. Unfortunately, the price also increases with the configuration and quickly reaches 2000 Euros (~$2682) and so non-business customers will quickly lose interest. Thanks to a more spacious case compared to many other convertibles, the Revolve 810 G2 does not have problems with prolonged load and always remains at a pleasant temperature and quiet.

3rd

The light 11.6-inch (1.13 kg) Dell XPS 11-9P33 has 360-degree hinges like the Yoga models from Lenovo. Dell is the first manufacturer to incorporate a touch keyboard into a conventional chassis. Not everybody will like the low feedback: The keys don't have any travel, but they are clearly palpable. The tester praised the versatility and the excellent build quality of the XPS 11. The sharp, bright display with wide viewing angles and a resolution of 2560x1440 pixels is impressive. The battery life ranges from six to ten hours. However, the processor throttles at relatively uncritical temperatures. Thanks to a lightning-fast SSD, standard users will not notice this, though.

4th

The 12.5-inch Lenovo ThinkPad Yoga combines the 360-degrees solution of the consumer Yoga with the business qualities of a ThinkPad. The latter includes very good build quality and input devices. The Yoga ThinkPad features stable metal hinges and a concealable keyboard. The latter ensures that the underside is almost completely flat without disturbing key travel in tablet mode. The battery life of 7:35 hours is very long (i5 model). The very bright IPS panel with wide viewing angles is another advantage. The touchscreen has an FHD resolution and is slightly non-reflective. So, it is nearly perfect for outdoor use. The price depends on the configuration. The model with Core i5 and 256 GB SSD starts at 1249 Euros (~$1675, cheapest configuration). The only weakness is the few interfaces (no Ethernet). But, Lenovo's power-adapter docking solution can help here. We assigned our Editors' Choice award to the ThinkPad Yoga in January 2014, since it is a good bundle with (almost) matte touchscreen, stable hardware and long battery life.

When notebook and tablet fuse: Fujitsu Lifebook T904

5th

Similar to the ThinkPad Yoga, Fujitsu targets well-funded business customers with its Lifebook T904. Instead of a 360-degrees hinge you get a classic single hinge in the center. The expectations are pretty high for 1800 Euros (~$2413). Fujitsu equips its T904 with a Core i7, large SSD, IGZO panel (2560x1440) and Sierra Wireless AirPrime. The mobile CEO gets good input devices, but they cannot quite keep up with the perfect feedback from the EliteBooks or the ThinkPad T-series devices. The panel with very high contrast and razor-sharp details is not perfect: The brightness could be higher (outdoor use) and the viewing angles could be wider.

6th

Sony's Vaio Tap 11 achieved the same total rating of 82% as the T904 in our review. While it features a good display and a slim shape, the battery life of about 5 hours is relatively low, the fan is loud under load and the performance is limited (no CPU Turbo).

7th

The Haswell upgrade of Lenovo's IdeaPad Yoga 11S brings significantly longer battery runtimes, but a performance gain is not noticeable. The device is still bulky and heavy in tablet mode, and the keyboard only features a weak feedback. But, the hinge design is clever, the build quality is stable, and the display has wide viewing angles (IPS).

Android + Windows: Transformer Book Trio TX201LA
Android + Windows: Transformer Book Trio TX201LA

8th

The 11.6-inch Transformer Book Trio TX201LA combines "the best from both worlds": An Intel Atom runs Android 4.2 inside and a fast Core i7 works in the key dock for Windows 8. The units can be used separately: The small PC station can be used with an external TFT, while the tablet is used on the move. Asus incorporated a handy data interface between the operating systems. In addition, we liked the high-end aluminum case and the good keyboard (distinct feedback). The emissions are low and the connectivity, including micro-HDMI and mini-DisplayPort, is noteworthy. Windows is installed on a 500 GB hard drive, which unfortunately decreases the system performance. The Transformer Book Trio is one of only two convertibles in our top list with an HDD (eMMC in the tablet).

9th

Many pros make the Asus Transformer Book T300LA interesting: high-end metal chassis, good system performance, very long battery runtimes of more than 10 hours in realistic scenarios, and the good display, which, however, is too dark. You have to do without several features, which the predecessor included: supplement battery and additional hard drive in the keyboard dock.

Entry-level Bay Trail: Lenovo IdeaPad Yoga 2 11
Entry-level Bay Trail: Lenovo IdeaPad Yoga 2 11

10th

Lenovo tries to offer a compact convertible for a small price. The result is the IdeaPad Yoga 2 11, an 11.6-inch device with the frugal and inexpensive Bay Trail platform, hard drive (ultra-thin) and IPS panel with the standard HD resolution. Similar to all Yoga devices you can open the display by 360 degrees, so the keys are facing downwards when you use it as a tablet, which slightly affects the haptic impression. The automatic lowering of the keyboard that we know from the ThinkPad Yoga is not available in this price range. Massive metal hinges, sturdy case and bright IPS display with a good contrast, we like those aspects. Lenovo also uses a conventional HDD instead of an SSD to keep the price down, which affects the system performance. Another positive aspect is the passive cooling solution. So the perfect Windows tablet for the road and your home? Not quite, the bouncy keyboard and the limited port selection may affect the handling quite a bit.

expensive: Toshiba Portégé Z10t-A2111

Acer's Aspire Switch 10 SW5-012-13DP is the FHD sister model of the previously tested Switch 10 SW5-011-12VU (HD panel). During our review, we scrutinized the new IPS panel and found a bright FullHD display with vibrant colors, which is unrivaled in this price range. The processor got a bit slower, but the battery life got longer. 

Our US colleagues reviewed the Toshiba Protégé Z10t-A2111, an expensive business convertible consisting of tablet and keyboard dock. The outside does not differ much from the previous Portégé Z10t's, but the manufacturer uses Haswell hardware inside now. We liked the matte 11.6 inch touch panel with vibrant colors, but the build quality is below average and the keyboard does not meet the high standards of the high-priced range.
