Notebookcheck's Top 10 Convertibles

Staff (translated by Martina Osztovits), 07/24/2015

July 2015 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 technologies allow 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

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. The successor, the Surface Pro 4, might be launched in October.

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.

Classic: HP EliteBook Revolve 810 G3
Classic: HP EliteBook Revolve 810 G3

HP's EliteBook Revolve 810 G3 is a classic with its swivel hinge. The 11.6-incher is relatively heavy at 1.4 kg and also the bulky height of 22 mm does not appear to be relevant in the business range. But, the Revolve 810 delivers where it is important: a bright, contrast-rich IPS display accompanies a very good keyboard. The fast SSD certainly works silently. The Intel Core i7-5600U usually does so, too, although it is actively cooled. The processor is not a Core M. The device hardly gets warmer and even has a maintenance hatch.

A 3-year warranty completes the bundle but is to be expected for a price of 2270 Euros (~$2580). The low HD resolution of the Revolve 810 G3 is absurd. Currently, FHD is not even an option. Sometimes, things are different in the business range and the consumer range. So, HD could actually be the preferred choice of users for 11-inch devices. Is the device too expensive for you? The Fujitsu Lifebook T935 convertible is an alternative (200 Euros, ~$227, cheaper).

Microsoft Surface 3
Microsoft Surface 3

Is the Surface 3 the next generation of notebooks? With Kickstand and optional Type Cover, the Surface 3 should be able to replace a laptop - at least in a low-performance scenario. Actually, the progress bar often appeared to be stuck during copying and installations. This is not due to the brand new and faster Intel Atom x7 Z8700 (Cherry Trail). The Surface 3 is slowed down by its slow eMMC. This is annoying since the performance would be easily sufficient for everyday tasks otherwise. Charging is slow, too. Since the power adapter is too small, the battery needs eight hours (device in use) for a full charge.

In real-world use during a multi-day air journey with many different locations, we constantly faced the problem of not getting enough energy into the device during possible charging periods for being able to work on-the-move for a longer period of time afterwards.

Apart from these big weaknesses, the Surface 3 also has a lot to offer. We appreciated the high-end case and the very good display. The good battery life of about seven hours in the Wi-Fi test is convincing and the silent operation is still standard for Intel Atom devices. The expensive bundle also includes an update to Windows 10 as well as Office 365 for one year.

Geforce Business: Lenovo ThinkPad S3 Yoga 14
Geforce Business: Lenovo ThinkPad S3 Yoga 14
Editor's Choice in July 2015: Lenovo ThinkPad S3 Yoga 14 with Geforce 940M
Editor's Choice in July 2015: Lenovo ThinkPad S3 Yoga 14 with Geforce 940M

Lenovo's ThinkPad S3 Yoga 14 presents itself as business convertible. It brings the 360 degress hinge of the consumer world into the business range. Those who want to profit from this flexibility in the workplace, do not have to dig that deep in the pockets: The entry level model with i5 and hybrid SHD is available from 999 Euro, the premium model with Geforce 940M, 256 GB SSD and same CPU costs 1130 Euro without operating system. The tester liked the elegant metal chassis combined with flexible and stable hinges very much. As befits a ThinkPad, the input devices feature an excellent feedback. Even the speakers of this business device sound good. The semi-reflective touch display has an acceptable contrast, good colors and wide viewing angles thanks to IPS technology.

The very good battery life is just under eight hours in the WiFi test. Fast SSD and gaming capable graphics card give a powerful bundle. The included Active Pen emphasizes the ThinkPad S3 Yoga 14's professional claim. This pen, which can be stored in the device (mounting), allows precise working on the desktop, since the 14-incher is also available without operating system.

Dead smart: HP Spectre 13-4001ng x360
Dead smart: HP Spectre 13-4001ng x360

Those who want all this in one - 13-inch notebook, tablet, high-end case, and long battery life - can stop searching. With the HP Spectre 13-4001ng x360, there is a convertible on the shelves which could even delight our tester. The robust, good-looking uni-body case with a low weight is a pleasure, since many will look at it with envy. Like with the Lenovo, several modes are possible thanks to the 360-degree hinge. There are many interfaces for a 13-incher. Mini DisplayPort, dual-band Gigabit Wi-Fi, and Ethernet via adapter can even satisfy special requirements.

The TFT has a resolution of 2560x1440 pixels and has very wide viewing angles thanks to IPS. However, the contrast suffers from the high black value and is only 549:1. The color representation compared to sRGB is not perfect, but profiling or our color profile can significantly improve it.

It is easy to open the case (bottom panel, screwed), which makes maintenance partly possible. The input devices with strong feedback (HP Control Zone - ClickPad) can also satisfy professional typists (quiet). Everybody will like the bright QHD IPS display with strong colors. Wide viewing angles and great colors please the eyes. The 13-incher is fast enough for Office and more and the SSD does a good job. The quiet fan was only annoying for the tester during the stress test. While idle, passive cooling is sufficient most of the time and the convertible falls completely silent.

The poor sound of the speakers and the glossy display surface (sometimes troublesome outdoors) belong to the disadvantages. The Spectre 13-4001ng x360 delivers a good price-performance ratio for currently 1249 Euros (~$1419), but it is not significantly better than the Aspire R13 R7's or Transformer Book 300 Chi's. However, HP has a more high-end and more elegant case.

Toshiba Portege Z20t-B-10C
Toshiba Portege Z20t-B-10C

Expensive runtime wonder was the title our tester chose for the Toshiba Portege Z20t-B-10C. The 12.5-incher does not feature a fan and is equipped with an Intel Core M 5Y71 (Broadwell) and a 256 GB SSD. So, there is an acceptable processing performance inside. Together with the keyboard dock and the digitizers, this gives a fully fledged work device. In addition, the battery life of just under 13 hours in the Wi-Fi test is impressive. It was made possible by the supplement battery in the dock and the frugal Core M.

Careful build quality, high-end input devices and the anti-reflective IPS panel with flawless image quality are pleasing. However, they cannot justify the extremely steep price of 2000 Euros (~$2273). Customers only get a 12-month warranty and not even a fingerprint reader. At least the connectivity is very good for a convertible with LTE module, HDMI, VGA and type-A USB. Unfortunately, the Z20t does not bring maintenance possibilities and the batteries are fixed.

For workaholics: Acer Aspire R13 R7-371T-779K
For workaholics: Acer Aspire R13 R7-371T-779K

Acer's Aspire R13 R7-371T-779K is a versatile all-in-one hybrid, i.e. it is tablet, notebook and multi-mode laptop in one device. The display can be rotated around its long axis, which allows many different positions. We liked the delicate-looking, yet stable and premium chassis. The input devices perform just as well and even office workaholics could be satisfied with them. Thanks to its versatility, the Aspire R13 is suitable as a work device, but with two SSDs in RAID-0, Core i7-4510U (Haswell) and 2560x1440 pixels in the display, it already aims at professionals who know exactly when they benefit from a 3K touch panel (WQHD). The display features natural and vibrant colors with hardly any clouding despite good brightness. The price of 1500 Euros (~$1705) is very ambitious, but you'll get a premium convertible including Acer's Digitizer Pen.

Tablet master with Zen design: Asus Transformer Book T300 Chi
Tablet master with Zen design: Asus Transformer Book T300 Chi

Not too small, but not too big and with the stylish and popular Zen-design. The 12.5-inch Asus Transformer Book T300 Chi wants to accomplish this. It weighs 1.4 kilograms (with the dock) and we like the thin construction, the WQHD screen and the HDMI output, but the runtime of around 4 hours is disappointing. Asus does not equip the small dock with a secondary battery, so 12.5-inch rivals like the ThinkPad X250 and the Acer Aspire Switch 12 are much better in the WLAN scenario compared to the T300 Chi.

The T300 Chi has some drawbacks: The magnet hinge appears a bit wobbly, the keyboard dock does not have additional features or ports, the keyboard only has a limited travel, the performance is reduced on battery power and the touchpad is pretty small. Business customers will prefer the Surface Pro 3; Asus does not offer WWAN and GPS modules or a stylus. What's left is a versatile Windows tablet with a good build quality, a great display and a fanless construction.

Flexible but still standard: Lenovo ThinkPad Yoga 12
Flexible but still standard: Lenovo ThinkPad Yoga 12

Lenovo's ThinkPad Yoga 12 is the smallest device from the new ThinkPad-series, which is available in 12, 14 as well as 15.6-inches and uses a 360-degree hinge. Convertibles do not seem to be only a gadget for private users anymore. Business users are supposed to use the flexible devices as well if you ask Lenovo. This might actually work with the 12-inch device because the manufacturer can use its strengths like the good input devices, anti-reflective surface and picture quality. The Full HD IPS panel is very bright but still has a good contrast. The touchscreen is complemented by a digitizer pen, which is a useful addition. The battery is integrated, but you can access it and other components when you remove the bottom cover.

A problem is obviously the pretty high weight of 1.58 kilograms, which is very heavy when you want to use it as a tablet in one hand. TPM is, unfortunately, the only security feature.
