Convertibles, also known as two-in-one or multi-mode PCs, are hybrids that can be used as a tablet or a laptop. There are many different kinds: docking tablets with a keyboard base, slider solutions over a fixed keyboard unit or clamshell chassis with a 360-degree hinge. Depending on their requirements, prospective buyers will certainly find the most appropriate solution for their needs. Many manufacturers offer docking tablets as well as 360-degree solutions. Lenovo has been a pioneer with its Yoga models for business and consumer sectors.

For battery life: Microsoft Surface Pro 4, Core m3
For battery life: Microsoft Surface Pro 4, Core m3
For performance with a fan: Microsoft Surface Pro 4, i5/i7
For performance with a fan: Microsoft Surface Pro 4, i5/i7

Microsoft's proposal for the next generation notebook has already advanced to the fourth round. The Microsoft Surface Pro 4 combines tablet and notebook in a highly mobile, handy shape. The Pro model of the Surface does not only stands out with its steep price, but also claims best possible performance. Performance-wise, it is supposed to be an adequate laptop replacement, which renders clamshell computers redundant. We have reviewed variants with frugal Core m3 (Skylake), Core i5 (Skylake) and Core i7 (see comparison). The m3 got the first place, since it remains cooler, is silent (fanless) and delivers a longer battery life.

The tester was delighted: Lower power consumption, silent operation, and longer battery life than the Core i5 model are apparent advantages. However, what is really positive is that the experienced performance is hardly different. The benchmarks show a tolerable disadvantage of only 20%.

There is no question that this is by far the best rendition of the Surface concept to date—and the first one that, despite limitations inherent to its design, might legitimately be considered as a suitable replacement for a conventional laptop.

If you are primarily looking for a Surface to replace a laptop on your desk and only occasionally take it to meetings, then the Core i5 version could be the better choice.

The display has been improved compared to the predecessor, again: It is not only significantly brighter, but it also delivers higher resolution, lower color deviation, and bigger gamut. The Type Cover has also been improved. Instead of a mediocre keyboard replacement, you will get a great input device, which can now keep up with Ultrabooks. For the first time, this is also true for the touchpad. Furthermore, the Surface pen is included in the scope of delivery.

Compared to a laptop, the connectivity is poor with only a single USB 3.0 port and a DisplayPort. The price is quite high and easily exceeds 1000 Euros (~$1125) with the Type Cover.

Slow eMMC memory: Microsoft Surface 3
Slow eMMC memory: Microsoft Surface 3

Is the Surface 3 the next generation of notebooks? With a 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 Intel Atom x7 Z8700 (Cherry Trail). The Surface 3 is slowed down by its slow eMMC. This is annoying since otherwise the performance would be easily sufficient for everyday tasks. Charging is also slow. Since the power adapter is too small, the battery needs eight hours (device in use) for a full charge.

In terms of practical use during a multi-day flight with many different locations, we were constantly faced with the problem of not getting enough energy into the device during possible charging periods to be able to work on the move for an extended period afterwards.

Apart from these major weaknesses, the Surface 3 also has a lot to offer. We appreciated the high-quality case and the very good display. A good battery life of about seven hours in the Wi-Fi test is impressive 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. Those preferring a larger size should consider the Surface Pro 4. The Surface Pro 4 has a slightly larger display (12.3-inch, resolution: 2736x1824) and is more powerful, thanks to a 6th generation Intel Core M3, i5 or i7 processor.

Dual companion: Microsoft Surface Book Core i7
Dual companion: Microsoft Surface Book Core i7

With the Surface Book (see review), Microsoft thinks of those for whom tablets/convertibles of the upper price range are still too slow. Will those who think that a Surface Pro 4 is too slow buy a Surface Book? This is the intention, even though performance geeks have to spend at least 1500 Euros (~$1690) for such a device (IGP version). The evaluated variant with a Core i7-6600U and NVIDIA Maxwell GPU (940M, GDDR5) currently costs 2920 Euros (~$3290). You will get a 1.5 kg (~3.3 lb) special convertible, which performs well as a tablet alone as well as with a keyboard dock and a dedicated GPU. This convertible PC delivers real laptop performance without throttling and full GPU performance even on battery.

The Surface Book i7 is almost 30% faster than the rivals Lenovo Miix 700 (core m3), HP Spectre X2 (Core m7) and Microsoft Surface Pro 3 (Haswell Core i5). The reason: The active cooling ensures a high Turbo utilization even during the stress test, while the fanless systems have to reduce their clocks.

The battery life is also long with 10 hours, and the 13.5-inch panel with 3000x2000 pixels delivers gorgeous colors. The latter shines with precise colors and high contrast (96% of sRGB). Since the input devices (including Digitizer Pen) are excellent, apparently you cannot complain at all, can you? The reviewers complained that the connectivity does not include USB-C or HDMI. The software undocking did not work flawlessly in our test and the poor upgradability is also a disadvantage. We have reviewed the following two models:

Challenger with GHz weakness: HP Spectre x2 12-a003ng
Challenger with GHz weakness: HP Spectre x2 12-a003ng
Surface Pro 4 competitor: Best Value Award for the HP Spectre x2 12 in February 2016
Surface Pro 4 competitor: Best Value Award for the HP Spectre x2 12 in February 2016

HP tries to offer a competitor to the leader - the Surface Pro 4. The handy Spectre x2 12-a003ng (K3D42EA9) (see review) certainly delivers. It comes with a brand new Intel Core m7-6Y75, which is just as frugal as the Core m3-6Y30 in the corresponding Surface Pro 4 model. Microsoft does not offer m5 or m7 variants. Is the Spectre x2 12 therefore an option for those looking for best possible tablet performance without a fan? Unfortunately, the answer is a clear no:

The computing power that only reaches that of the Surface Pro Core M3 is disappointing. The potential buyer might just as well opt for the m3-6Y30 version (2x 900 MHz) that is probably even more frugal in undemanding mobile use.

Nevertheless the Spectre x2 12-a003ng achieved quite a good result and impressed the tester. However, the Real Sense camera had the smallest impact on this. We liked the extraordinary good concept from keyboard (backlight, good haptics) and tablet. The combination is actually subnotebook-like and productivity use is comfortable without major limitations.

With its very stable stand and the sleeve keyboard that is "attached" to the tablet, the Spectre x2 can be used as a laptop on the table to a very high degree. The USB Type C ports recharge the device, and provide a cabled connection to existing Type A peripherals via a hub or an adapter (included). The primary camera on the tablet's back takes very nice photos and videos. We have not seen this for a long time in a Windows tablet.

All those who consider the Surface Pro 4 and want to spend a lot of money on a mobile work bundle, should take a closer look at the Spectre x2 12-a003ng. The disadvantages are acceptable in view of the advantages if you do not call yourself a power user and want to edit and render movies on this device.

The price of 1400 Euros (~$1583) is certainly not a bargain. You will also get a Surface Pro 4 with 256 GB for it, yet it does not even include the Type Cover. On the other hand, the Surface Pro 4 features 2736x1824 pixels, while the Spectre comes with only a Full HD resolution. The lower resolution does not need to be a disadvantage. Benefits of the HP are definitely its two USB 3.1 (Type-C) ports. A Stylus Pen is also included and there is a variant with LTE for the same price.

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-inch device is relatively heavy at 1.4 kg (~3.1 lb) and the bulky height of 22 mm (~0.9 in) does not appear to be relevant in the business range. However, the Revolve 810 delivers where it is important: a bright, contrast-rich IPS display accompanies a very good keyboard. The fast SSD 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 warm and even has a maintenance hatch.

A 3-year warranty completes the bundle. However, a starting price of 1750 Euros (~$1969) is to be expected. 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. Therefore, HD could actually be the preferred choice of users for 11-inch devices. Is the device too expensive for you? A business quality alternative could be for example, the Toshiba Portégé Z20-B convertible further down in the 8th place.

Cheaper than the SP4: Best Value Award for the Lenovo IdeaPad Miix 700 in February 2016
Cheaper than the SP4: Best Value Award for the Lenovo IdeaPad Miix 700 in February 2016

Lenovo has also noticed it: Its competitor Microsoft is very successful with the Surface Pro family – despite a high price. The Lenovo IdeaPad Miix 700 targets the same customers with a price from 940 to 1400 Euros (~$1058 to ~$1575, 256 GB / 4G/LTE). These are the customers who are looking for the best possible laptop replacement. It should make switching between two devices and the annoying synchronization with online storage unnecessary.

For this high requirement, Lenovo has decided to use a fanless design, but has used a more powerful CPU than the m3 in the Surface Pro 4 entry-level model. The performance of the Intel Core m5-6Y54 is closer to the Core m3's than to the Core i5's. Thus, the performance cannot completely reach an optimal notebook level. However, most users will not mind, since the system performance only differs from the Surface Pro 4 (Core i5) by 16 and 22% (PCMark 8/7), respectively. The genuine M.2 SSD from Samsung has a positive impact here. Permanent load is not the strength of the fanless IdeaPad Miix 700. Its performance falls slightly in this scenario. The performance loss of the HD Graphics 515 is particularly disadvantageous. It always works disappointingly slow in our test model.

Furthermore, the tester likes the concept of the tablet and keyboard dock. All models come with an ActivePen and several variants include a Real Sense camera (not in our test model). The Miix 700's display is bright, contrast-rich, and viewing-angle stable. Out-of-the-box, the colors require calibration. The battery life of about 7:20 hours in our WLAN test is quite good and almost on par with that of the Surface Pro 4.

In the opinion of our tester, the Miix 700 is a close competitor of the Core m3 Surface Pro 4. There is no clear winner. The Miix 700 is cheaper and a 4G/LTE variant is available, while the Surface Pro 4 features the better display and a higher quality case.

Elite business features: Editor's Choice Award for the Lenovo ThinkPad Yoga 260 in February 2016
Elite business features: Editor's Choice Award for the Lenovo ThinkPad Yoga 260 in February 2016

With the ThinkPad Yoga 260, Lenovo launched another convertible. However, it is targeted at very demanding business customers. The ThinkPad does not tolerate compromises that the IdeaPad Miix 700 still makes. Thus, the Yoga 260 is a genuine subnotebook, which can be turned into a tablet with a 360-degree hinge. Lenovo makes the thick tablet with the keyboard on its underside less awkward by fixing the keys. They are flush with the underside and can no longer be pressed.

Excellent input devices, including an active stylus – the tester did not expect anything else from a ThinkPad. Unfortunately, the stylus generates a big problem: The chassis tears easily at the stylus compartment. Further disadvantages include heavy CPU throttling, even during usual processor tests. The colors of the TFT are not the best. Beyond that, you cannot complain about the matte, bright touchscreen. A poor webcam and distorted microphone recordings slightly dampen the impression, but they are not factors that discourage from buying.

Then there is the issue of CPU throttling during normal load. Why should the fastest 15-watt i7 be purchased if it cannot deliver what it promises?

The positive aspects are that the system can be individually configured, the dedicated docking port, the security features, and the low system noise. Not least, the Yoga 260 appears to be interesting due to its attractive entry-level price of about 1100 Euros (~$1238, Lenovo Shop, i3 version, no HDD variant!). HP and Fujitsu charge about 500 Euros (~$563) more to provide the business features the Yoga 260 offers. Thus, we assigned it our Editors' Choice Award in February 2016.

When the budget is "only" 1000 to 1500 Euros (~$1125 to ~$1688), the Yoga 260 is a good choice. Its entry-level configuration is relatively affordable and features professional business qualities that HP and Fujitsu provide at approximately 2000 Euros (~$2251).

Without fan: Toshiba Portege Z20t-B-10C
Without fan: Toshiba Portege Z20t-B-10C

A lot of money for long battery life. Toshiba charges 1700 Euros (~$1916) for the Portege Z20t-B-10C. The Convertible consists of a tablet and a keyboard dock. The latter delivers many interfaces and a second battery (36 Wh + 36 Wh), which also contributes to the brilliant battery life of 12:40 hours in the Wi-Fi test. However, this is not the only impressive feature: An anti-reflective touchscreen (FHD) with flawless image quality leads the pro list. High-quality input devices, accurate build quality, and very good performance in everyday tasks with passive cooling follow. However, the Surface Book and the Surface Pro 4 are faster, since they feature cooled 15-watt processors and the Surface Book also comes with an Nvidia GPU. The reviewers could only complain about the non-existent upgradability and the short warranty of only 12 months.

All things considered, the Portege Z20t might first and foremost be interesting for rich business customers looking for a versatile work device with maximum mobility. Consumers that can do without security and other features will get cheaper alternatives from competitors.

4K for on-the-move: Dell XPS 12 9250 4K
4K for on-the-move: Dell XPS 12 9250 4K

With the XPS 12 9250 (see review), Dell has complemented the XPS series of 13.3 and 15.6-inch devices with a smaller one. The 12-inch device is a tablet with a docking keyboard, which features a Core m7 and does not need a fan. Thus, it is silent. With 8 GB of RAM and a 512 GB SSD, the elegant and handy device delivers cutting-edge hardware. However, the 4K panel (3840x2160) caps it all off. High contrast, good color coverage, and wide viewing angles delight the viewer. Prospective customers should also consider the smaller CPU options (i5, i3), since the used Core m7 cannot reach its full performance due to thermal throttling anyway.

Although the review sample is equipped with the strongest processor from Intel's Core m lineup, the performance cannot be completely retrieved. Thus, Microsoft's Surface Pro 4 with a Core m3, for example, is sometimes much faster.

The keyboard dock is stable and can be seamlessly attached to the tablet. It delivers a quiet keyboard and a precise touchpad. The tilting angle cannot be adapted to the seating position, since it is fixed.

Dell demands an exorbitant 1799 Euros (~$2051) for the test configuration. This is definitely not a bargain, but it is one of the few devices with a 4K panel in a 12.5-inch size - if that is the driving force.

Rarity: Acer Aspire R13 R7-372T
Rarity: Acer Aspire R13 R7-372T

The Aspire R13 is a versatile All-in-One, i.e. a tablet, notebook, and multi-mode laptop in a single device. The display can be turned and swivelled across its longitudinal axis, which allows different positions. We liked the delicate looking, yet stable and high-quality chassis. The input devices can keep up with it in this aspect and even office workaholics can be satisfied with them. Due to its many operating modes, the Aspire R13 is suitable as a business device for work. With two SSDs in RAID-0, Core i5-6200U (Skylake), and 1920x1080 display, it attracts many customers. The latter provides natural and vivid colors.

The convertible does not get very hot and remains fairly quiet as well. The RAID 0 SSD array guarantees a very fast system and short application load times.

The Thunderbolt 3 port is implemented as a cutting-edge USB 3.1 Gen2 Type-C. Thanks to it, users can expand the convertible in many ways. At just under 1100 Euros (~$1238), the Acer is affordable. You will get a premium convertible. Unfortunately, Acer's Digitizer Pen - contrary to the information in many online shops – is no longer included.

In addition to the FHD variant, we have also had a look at the 4K model (Aspire R13 R7-372T-746N – see review). The high-resolution display impressed the tester with its high contrast, high brightness and almost 100% sRGB color coverage. It is one of the best IPS panels in this class, which we have reviewed in the last months. Even the displays of the Dell XPS 13 4K and the Asus ZenBook UX305CA (4K) cannot reach its quality. With 4K, Core i7-6500U, and 256 GB SSD, the battery life is about 15% lower than the FHD models, but, the total rating is the same thanks to the better display.
