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.

Editors' Comments

Those who want a Windows Tablet do not want low performance to get them stuck in the very first app. Thus, there are many devices with real SSDs and Core m or Core i processors (with/without fan) in the market. All models listed in this top list offer notebook performance - at least, almost. Intel Atom devices are not represented here. The Surface 3 left the charts since its review is older than 12 months. Its performance is primarily suitable for web surfing and typing texts.

The ASUS Zenbook Flip UX360CA (Core m3, see review) is an exciting device, which missed the top list by a small margin: A rating of 83 % is too low. We particularly disliked the clattery keyboard and the battery life of "only" 6:30 hours. The Lenovo Yoga 900S-12ISK (see review) has a similar fate. While the very slim 360 degrees convertible with watchband hinge lasts just under 10 hours, its SoC throttles heavily and the keyboard feedback is too low. We are expecting models of the Asus Transformer series, in particular the Transformer 3 Pro (12.5 inch, Core i), to arrive in our lab soon.

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 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 it 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.

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 (~$1120) with the Type Cover.

The Acer Aspire Switch Alpha 12 (2nd place) might be the better choice for consumers: It brings the performance of a 15 Watt SoC without fan and only costs 800 Euros with i5 and 3K panel. Consumers should also consider the Spectre x2 12-a003ng (5th place) as Surface Pro 4 alternative. The 12-incher currently costs 1100 Euros (~$1232). Professional users probably might find in the more expensive HP Elite x2 1012 G1 (4th place) the strongest competitor. It features a lower resolution, but Type-C USB and LTE (version).

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 (~$1680) for such a device (IGP version). The evaluated variant with a Core i7-6600U and Nvidia Maxwell GPU (940M, GDDR5) currently costs 2920 Euros (~$3270). 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 at 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:

Microsoft Surface Book Core i7, 940M

Microsoft Surface Book Core i5, 940M

Discussion

Go-getter type: HP Elite x2 1012 G1
Go-getter type: HP Elite x2 1012 G1

With the Elite x2 1012 G1 (see review), HP brings a powerful competitor to the Surface Pro 4 and the Switch Alpha 12. While it is not cheaper at just under 1500 Euros (~$1680), it brings more interfaces yet smaller resolution. The tester was satisfied with the actual performance of the passively cooled Intel Core m5-6Y54. Only the Lenovo IdeaPad Miix 700 was an exception in this aspect with heavier performance losses. The performance is comparable with the Dell XPS 12 9250 and the Samsung Galaxy Tab PRO S (just missed the top list), which are also passively cooled. Microsoft's Surface 4 Pro and the Switch Alpha 12 bring a higher performance thanks to Core i processors, but the Core m variant is slower than the Elite x2 1012 G1.

The keyboard dock with strong feedback and backlight is well made. Very good battery life of 7:30 hours (Wi-Fi test) and an LTE modem (depending on the version) make the bundle complete, which primarily targets professional users who demand very high mobility.

The display could be improved, however. It's not that this panel is particularly bad - but considering the price, we expect a little more as far as the brightness and the contrast are concerned.

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 also offers a competitor to the Surface Pro 4 for consumers. 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 1150 Euros (~$1288) 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 for just under 1300 Euros (~$1456). 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. Acer's Aspire Switch Alpha 12 SA5-271 performs better in this aspect again. The fanless tablet costs only 775 Euros with Core i5 and 3K panel, the variant with i7 and 512 GB SSD is priced at 1250 Euros.

Just missed the lead! Lenovo IdeaPad Miix 700

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 (see review) targets the same customers with prices from 940 to 1400 Euros (~$1052 to ~$1568, 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. Those who like the concept of the Miix 700 should also consider the HP Spectre x2 12-a003ng. This 12-incher does not bring a top performance, but it has a better build quality and USB Type C. Those who want to save money, can consider the Acer Aspire Switch Alpha 12 SA5-271 with higher CPU performance and also fanless operation.

Multi-mode master: Lenovo ThinkPad Yoga 260

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 (see review), 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 (~$1232, Lenovo Shop, i3 version, no HDD variant!). HP and Fujitsu charge about 500 Euros (~$560) 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 (~$1120 to ~$1680), 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 (~$2240).

8th

High CPU performance: Lenovo Thinkpad X1 Yoga
High CPU performance: Lenovo Thinkpad X1 Yoga

ThinkPad X1 goes Yoga. Lenovo replaces the hinges of the ThinkPad X1 with a 360-degree hinge and out comes the ThinkPad X1 Yoga (see review), from which we had a variant with Intel Core i7 6500U and 512-GB-SSD under review. The testers praised the solid and well designed business convertible made from carbon fiber and magnesium alloy, which includes an active stylus. The high performance of the actively cooled Core i processor and the high color and grayscale precision (after calibration) of the 2560x1440 display are attractive. Certainly, the 1.36 kg device is not as lightweight as the Surface Pro 4 (1.1 kg) or the HP Elite x2 1012 G1 (1.2 kg with keyboard dock). In return, the 14-incher is perfectly suitable for work with many interfaces (yet no Type-C USB) and a premium keyboard with backlight.

The ThinkPad X1 Yoga does what it was designed for rather well - but for a price.

Unfortunately, there also are disadvantages: The ThinkPad X1 Yoga loses points because of the mediocre battery life of six hours (Wi-Fi test) and the not especially bright display. The high price of 1950 to 2300 Euros (~$2184 to ~$2576) might discourage many prospective buyers. Thus, the author recommends the HP Spectre x360 13, which is targeted at consumers, as a cheaper alternative (about 1000 Euros, ~$1120). There are hardly any alternatives with similar size (14-inch) and similar performance (Intel Core i): HP's EliteBook Revolve 810 G3 also weighs 1.4 kg but features a no longer up-to-date HD resolution and is only an 11.6-incher. The Portégé Z20t-B-10C has a weaker performance and the 12.5-incher weighs 1.5 kg.

9th

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 furnished 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. We would also have hoped for longer battery life. The battery performance should be somewhat better in a tablet that is also marketed for the business sector.

The keyboard dock is stable and attaches seamlessly 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. That 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. Consumers might consider the Acer Aspire Switch Alpha 12 SA5-271 for half the price. It brings 3K from 775 Euros.

10th

moved up: Samsung Galaxy Tab Pro S W700N
moved up: Samsung Galaxy Tab Pro S W700N

Previously, the Samsung Galaxy Tab Pro S W700N (see review) missed the top list by a small margin. The 12-inch model is the only Windows convertible of this manufacturer. As old devices have been removed from the top list (12 month), the Galaxy Tab Pro S gets involved here as well now. However, it has its weaknesses: Despite an impressive AMOLED display, which makes for a display rating of 86%, it does not perform well enough for a top position. This is due to weaker performance - than for example the Surface Pro 4 - poor connectivity (one USB-C port for data and charging), and the not entirely perfect keyboard. Those who contemplate the Core m3 model of the Surface 4 should also consider the Galaxy Tab Pro S W700N.

The AMOLED screen on the Galaxy TabPro S is the key feature here. It's bright and punchy and if you're careful you can get impressive efficiency from it. Style plays a big role too.
