Lenovo Yoga Book

We’re so happy that we live in the same world as the Lenovo Yoga Book, and we don’t just say that because it’s extremely affordable right now – even ahead of all the Black Friday and Cyber Monday 2018 deals. No, the Lenovo Yoga Book is worth your attention as it’s the unlikely combination of a tablet and a laptop in a way never seen before – and may never see again.

Suffice to say, it’s a device that’s made a name for itself on TechRadar, having made its way onto our best laptops of 2018 list. But, why do you think that is? 

However, even though it’s a convertible device, the Lenovo Yoga Book doesn’t have a physical keyboard – at least, not in the way you may expect. Instead, the Lenovo Yoga Book features this unique hinged keyboard and trackpad completely free of travel – as it’s completely digital. That may sound awkward and hard to adjust to – and, well, it totally is.

However, with its low cost, it’s actually worth the effort – and we’ll dive more into that in a while – especially with its inputs separate from the screen that you can use as a Wacom digitizer. Of course, cooking up its own, all-new category of laptops is a full-time job, and we wouldn’t advise writing off the Yoga Book. After all, breaking new ground will always take some getting used to. 

And finally, this is the first laptop or tablet to come in both Windows 10 and Android varieties using the exact same hardware inside.

That’s quite a lot of firsts for a 10.1-inch productivity device that costs just $499 (about £409, AU$655; Android) or $549 (about £450, AU$720; Windows 10) to start. There has to be a catch, right? 

Of course there is, but let’s focus on what makes the Yoga Book so awesome first, shall we?

Design 

The Yoga Book, at first glance, looks like every other Lenovo Yoga laptop – only smaller. The impressive, gorgeous watchband hinge first introduced with the Yoga 3 is present and correct, and the insanely thin device is wrapped in a smooth, luxurious magnesium alloy shell like so many Yoga devices before it.

The Android edition of the Lenovo Yoga Book, which we’d guess Lenovo expect to sell more, comes in Champagne Gold, Carbon Black and Gunmetal Gray finishes. The Windows 10 edition just comes in Carbon Black – but all of these finishes look fantastic.

[Editor’s Note: This review focuses on the Windows 10 version of the Yoga Book, with salient differences in the Android Marshmallow version noted.]

A power button and volume rocker on the device’s right side are edged in chrome, and speakers sit behind dotted grilles on either side of the keyboard deck. The speakers pump out suitable range and volume despite their size, thanks to Dolby Atmos technology inside.

Another impressive feature about the Yoga Book despite its size is the 10.1-inch, 1,920 x 1,200 resolution screen. With 400 nits of brightness and the capability to display a range of 16.7 million colors, HD movies look excellent on the Yoga Book, and in-plane switching (IPS) means wide angles for screen sharing.

Tactile touch typing  

For those of you doubting whether an entirely digital, capacitive keyboard can cut the mustard, stop right now. In our time with both versions of the Yoga Book and its Halo Keyboard, we were surprised by just how accurate we found typing without any sort of physical buttons or feedback.

Sure, there’s haptic feedback and audio cues that signal when typing, like on a smartphone, which can be toggled on or off. But, neither completely account for how accurate we are typing on this backlit digital keyboard, behind a sheet of Gorilla Glass with individually lit keys.

If anything, our accuracy is testament to our growing aptitude with digital keyboards since the dawn of smartphones and tablets – only this one doesn’t take up half the screen. (Lenovo’s patent-pending hardware and software helps a great deal here, too.) 

Even without auto-correct software on the Windows 10 version, we found ourselves making very few errors while working on the Yoga Book. Of course, it’s unrealistic to expect the same words-per-minute speed that you would attain on an analog keyboard, and we don’t expect everyone to have the same easy transition that we had. The Android version’s Lenovo-made TouchPal auto-correct software should help a great deal with that acclimatisation. 

This, then, brings us to a question: if all versions of Windows 10 are essentially the same operating system (OS), why then is Windows 10 Mobile’s excellent auto-correct software not available on all versions of the OS?

As for the Android version, we in fact not only found the built-in auto-correcting software to be extremely helpful, but practically essential after getting used to it being there. 

However, in order for said keyboard to work properly, we had to disable all international keyboards. Otherwise, certain key presses would register whatever the key is next to it on-screen. At least this workaround solved the issue.

At any rate, we found navigating and typing on the Yoga Book surprisingly easy after about an hour with the device. Of course, you’ll find differences between both keyboards – i.e. the Windows 10 version’s left and right mouse buttons that allow for click-and-drag and the Android version’s lack thereof – but both offer the same fidelity.

The Wacom digitizer is wonderful 

It’s fine enough that the Yoga Book is the first laptop or tablet to include a keyboard that doubles as a full-blown Wacom digitizer. It’s even better that the tool is a joy to use, not to mention that it has one super-neat trick up its sleeve.

Pressing and holding a capacitive button above the keyboard with a pen icon switches the tool from displaying the keys to displaying, well, nothing but an illuminated pen icon. This means you can now use the surface to draw or write with the included Real Pen stylus.

Lenovo calls this the Create Pad, a layer of electromagnetic resonance (EMR) film beneath the keyboard that’s powered by Wacom Feel technology. This means that the Real Pen needs nothing inside to operate, with the Create Pad doing all of the work – even the 2,048 levels of pressure sensitivity.

The Create Pad offers the supreme palm detection artists have come to expect from the brand, and has differing levels of support from the Yoga Book depending on the version. The Windows 10 version supports the Create Pad in all apps that would support stylus control, like Windows Ink, but specifically calls up OneNote when activated.

On Android, however, Lenovo seems to have enjoyed a lot more freedom in custom-tailoring software for the OS, with Lenovo’s home-grown Note Saver app for note-taking and drawing.

Regardless, both versions of the Yoga Book are capable of one aforementioned, seriously cool trick: taking scrawlings in pen on paper and digitizing them for later access, editing and backup. This is made possible through an included magnetic notepad that attaches itself to the Create Pad’s surface, and included (office-standard) real-ink ballpoint tips for the Real Pen.

Now, this is where the EMR comes into play. As soon as the Real Pen touches the notepad – when attached to the Create Pad surface – whatever’s written is picked up by the electromagnetic response given off by the contact of pen to paper through the notepad’s magnetic rear surface, to be translated onto the screen via the Create Pad. The accuracy with which this is achieved is incredible, and it’s something you simply have to see in action yourself to believe.

With this feature, you can even fold the tablet in the reverse direction to use it simply as a traditional paper notepad with a digital backup. Using the tablet in this way even shuts the screen off, saving precious battery life – though, the Yoga Book already has gobs of that.

But, beyond note-taking, we could see this feature being a boon for artists that feel more at home drawing on paper with ink than a glass surface with a stylus, with the option to alter their work digitally later. Of course, this assumes a lot on the front of app and file compatibility.

All told, the Yoga Book’s Create Pad and Halo Keyboard are wowing tools that separate this tablet from the majority of 2-in-1 devices. Even more so, they stand to see Lenovo spur yet another standard in dual-purpose computing devices. 

But before we get ahead of ourselves, let’s see how this thing stacks up against some of the leading tablets, and what it’s like to use as a productivity device.

Look, we aren’t being hyperbolic about just how thin the Yoga Book is. It’s one thing to call out the 9.6mm (0.38-inches; closed) figure, but it’s another thing entirely to see and feel the device. For Pete’s sake, if it was much thinner the tablet wouldn’t be able to fit the included audio jack.

We’re talking nigh-iPhone levels – by a tenth of an inch – of thickness on each end here, folks.

That said, the iPad Air 2 is noticeably slimmer than this at 6.1mm (0.24-inches), as is a comparable Windows tablet, like the Samsung Galaxy TabPro S at 6.3mm (0.25-inches). On the Android side, among the thinnest is the Google Pixel C, at 7mm (0.27-inches). All of these devices are also lighter than the Yoga Book (1.52 pounds; 690g) by tenths of a pound – with Apple’s leading slate unsurprisingly taking the lead in lightness by more than a half-pound.

Spec sheet 

Now, let’s see what Lenovo managed to cram inside one of the year’s thinnest tablets. Here is the Lenovo Yoga Book configuration sent to TechRadar for review:

• Operating System: Windows 10 Anniversary Edition or Android 6.0.1 Marshmallow
• CPU: 1.44GHz Intel Atom x5-Z8550 (quad-core, 2MB cache, up to 2.4GHz with Turbo Boost)
• Graphics: Intel HD Graphics 400
• RAM: 4GB (LPDDR3)
• Screen: 10.1-inch FHD (1,920 x 1,200 resolution), IPS touchscreen
• Storage: 64GB flash storage (expandable by up to 128GB via microSD)
• Ports: microUSB, microHDMI, 3.5mm audio jack
• Battery: 8,500mAh
• Connectivity: 802.11ac Wi-Fi (2.4 & and 5GHz), optional 4G radio, Bluetooth 4.0
• Camera: 2MP front-facing webcam with fixed focus; 8MP rear camera with auto-focus
• Weight: 1.52 pounds (690g)
• Size: 10.1 x 6.72 x 0.38-inches (256.6 x 170.8 x 0.96mm; W x D x H)

As you can see, Lenovo has leveraged the same hardware to work with both Windows 10 and Android Marshmallow, but there is a difference in pricing for each. While the Android version costs a flat $499 (about £409, AU$655), the Windows 10 model asks for another 50 bucks at $549 (about £450, AU$720).

This is likely due to the fact that Microsoft charges its manufacturing partners for use of its Windows 10 operating system, whereas Google doesn’t charge vendors to use Android.

At any rate, either edition of the Yoga Book is comparable in price to key competitors, like the iPad Air 2 and Google Pixel C. Samsung’s Windows 10 tablet is far more expensive than this lot, though it’s a 12-inch device stacked up with 10-inchers.

That said, the Yoga Book offers more in some areas than its rivals and less in others. For instance, Lenovo’s tablet offers more memory (RAM) and storage than its two like-sized competitors to start, though its screen isn’t nearly as sharp, and its processor isn’t as powerful either.

Then again, neither of the two offer the Yoga Book’s unique features, so it’s rather difficult to get anywhere near an apples-to-apples comparison between this device and any of its rivals. 

For what this device offers in terms of original selling points over the competition, it’s excellent value. However, for everything unique about the Yoga Book, we’ve found it to be sorely lacking in power – so much so that it noticeably affects our experience using it.

Performance 

In our time using the Yoga Book (primarily the Windows 10 version), we’ve found the tablet more than ready to play full HD videos, handle basic web browsing and act as a brilliant drawing device – both digitally and with its clever analog-to-digital approach.

Unfortunately, attempting much beyond those functions, like our typical workload of 10+ Google Chrome tabs and using the Slack app to communicate with teammates, quickly reveals the device’s rather low power ceiling. And boy, will you feel it.

For a tablet touted for its ability to keep users productive, it has quite a bit of trouble keeping up with what we think is a basic workload for a Windows 10 device designed for productivity.

Here’s how the Lenovo Yoga Book performed in our suite of benchmark tests:

Benchmarks

• 3DMark Cloud Gate: 2,098; Sky Diver: 830; Fire Strike: Not supported
• Cinebench CPU: 117 points; Graphics: 15 fps
• GeekBench: 1,008 (single-core); 3,365 (multi-core)
• PCMark 8 (Home Test): 1,372 points
• PCMark 8 Battery Life: 8 hours and 32 minutes

While there isn’t much out there to compare most of these benchmarks against, we at least have Geekbench to bridge the gap between Windows 10, iOS and Android. Though, with both the iPad Air 2 and Pixel C’s multi-core processor results beating the Yoga Book by more than 1,000 points, that doesn’t do the Yoga Book any favors.

Clearly, the Yoga Book is a far worse performer in straight throughput against comparably-priced competitors. But, again, given that the Yoga Book is far from a straight-up tablet, we can’t fault the device too harshly for this.

What we can fault the Yoga Book for, however, is how this low power ceiling affects the entire experience when under such an aforementioned workload. Because the touch-based keyboard on offer here is an entirely digital affair, more of the CPU and RAM’s inherent overhead is dedicated to managing those input requests than is the case with an analog keyboard.

Regardless of how much overhead this actually amounts to, it’s woefully noticeable when, say, trying to write an email or even type a URL into the web browser while under such a workload as we mentioned above. The keyboard visibly lags behind our commands, and switching between typing and navigating via the touchpad takes more than a few presses before the touchpad responds.

(We find the same issue on the Android version, sadly, though it can handle a bit bigger of a load before buckling. However, it's blatantly clear that Google has some work to do before touchpads on Android devices are comparable to that of Windows in terms of speed and responsiveness.)

Frankly, this isn’t the sort of experience we expect from a device that promises to keep us productive. Granted, the word ‘productive’ is subjective, but we think that the tasks that keep us specifically productive shouldn’t be out of reach of a $550 (about £450, AU$720) device.

All told, if your workload is anything like what we’ve described above, don’t expect to be able to get it done on the Yoga Book without a bit of frustration. Here’s hoping Lenovo can address this somewhat through firmware patching – but, you can only push an Atom processor so far. That said, so long as you manage your expectations for what kind of work you can get done with the Yoga Book, your time with it might just be delightful.

Battery life 

What every user of the Yoga Book will be undoubtedly delighted by is the tablet’s lengthy battery life. Lenovo claims the tablet is good for up to 15 hours of life with general usage from its whopping 8,500mAh battery. Of course, vendor projections rarely, if ever, line up with real-world results, but the Yoga Book’s longevity is nevertheless impressive.

The PCMark 8 battery test, which simulates several computing tasks that we’d consider ‘general use’, put up a result of 8 hours and 32 minutes. That’s a far cry from 15 hours, but nevertheless it’s impressive for a Windows 10 tablet, much less any other.

In our anecdotal battery test, which plays a 1080p video on loop at 50% brightness and 50% volume, the Yoga Book lasted a cool 7 hours and 43 minutes. That’ll easily cover any national flight and some international.

While we haven't thoroughly tested the Android version's battery life, we see that it loses about 50% of its capacity after 4 hours. So, it's safe to expect about the same battery life here as we see from the Windows model.

Almost regardless of the task, you can expect the Yoga Book to last for an entire day’s worth of work (or play). Considering that our smartphones – and most laptops – can barely hang on through lunchtime much less the whole day, this is definitely an advantage for the Yoga Book.

Just strap in for some lengthy charge times on either version of the tablet – thanks to the microUSB port – to the tune of several hours. This is a shame, as USB-C offers fast charging and far more versatility than this dated connection standard. But, take solace in that you don’t have to charge the Yoga Book terribly often.

The Lenovo Yoga Book is, frankly, one of those devices that’s tough to critique given how different it is. This piece of hardware could very well become an entirely new subcategory within laptops and tablets – devices that bridge the gap between both in ways that today’s 2-in-1 laptops simply can’t.

Yet, the power profile of this first go sets certain expectations for what such devices are and should be capable of. That’s why we look at the Yoga Book as the first of what we’re calling the netbook of the future. The ultra netbook, perhaps.

Lightweight and low-power, netbooks came at a time just before the ubiquity of tablets and were quickly outpaced by them as the – literally and figuratively – de facto lightweight devices to get through email, write up brief documents and have some fun creating or gaming along the way. But tablets could never offer the screen real-estate that netbooks did while typing short of a Bluetooth keyboard.

Now, with the Yoga Book, it seems as if we’ve come full circle with a device that offers the functionality of both a netbook and a tablet in one beautiful package. However, we’re hoping that Lenovo’s second attempt at this can offer a bit more power.

We liked 

The Yoga Book’s versatility is unmatched in both the laptop and tablet worlds combined – in that it actually collides the two. Full-on touch laptop keyboards are something we in the TechRadar office used to joke about when seeing devices like the 2014 ThinkPad X1 Carbon’s row of adaptive function keys. Now, with the Halo Keyboard, we’re amazed at how accurate we are typing on it, even without any sort of auto-correct software on the Windows 10 version.

Plus, getting a Wacom digitizer and stylus attached to a plenty-sharp screen – that can digitize and back up ink-to-paper scrawling no less – for the price of an iPad is immense value. Throw in that it can handle your (albeit terribly basic) computing tasks like a laptop can, and that value only grows.

We disliked 

There isn’t a lot that we outright don’t like about the Yoga Book, but there are downsides which detract from an otherwise potentially revolutionary device. For one, it appears to us that Intel’s Atom chip is holding the Yoga Book back from its true potential. Perhaps upping the screen size to 12-inches next time would allow enough room for a more powerful Intel Core M series chip.

Second is that, with no analog keyboard hardware inside and the timing of its release, we’d expect to see such a groundbreaking device use the latest in connectivity: USB-C. Instead, we’re stuck with a port standard that is inferior in every way: microUSB. From slower data transfer speeds to woefully long charge times, microUSB only stands to hold the Yoga Book back from rewriting the book on 2-in-1 computing devices.

Final verdict 

If it weren’t for the underpowered processor inside and dated connectivity solution holding it back, we would outright say that the Yoga Book is both the Android and Windows 10 tablet to beat. And, for folks in the art world, we very well might say that anyway. 

The Yoga Book bridges the gap between tablet and laptop in ways that we, frankly, didn’t expect for a much longer time – if at all. The fact that we can type accurately on the Yoga Book’s Halo Keyboard, even without auto-correct software helping us, is testament to both Lenovo’s hardware and software engineering and our growing acuity with such input methods over the past decade.

Whether you buy the Yoga Book right now is a horribly difficult question to answer, as we want to see it succeed for the future of what could be an entirely new subcategory of devices. 

But, unless you’re a burgeoning digital artist looking for an all-in-one Wacom device, we’d say wait for a hopeful ‘Version 2.0’ with stronger components that would make more sense for all of us to get on board with.
