Look and feel
It's exactly what it sounds like, folks: It's a ThinkPad that looks like a Yoga, and a Yoga that looks like a ThinkPad. Got it? Good. Here's a quick tour. Unlike ThinkPads of yore, which had a soft, rubbery finish, the ThinkPad Yoga sports a smooth magnesium lid, though certain key details (the red TrackPoint, the glowing ThinkPad logo) have carried over. Also like older ThinkPads, it's fairly boxy, with blunt edges and straight lines (though Lenovo did sneak in some rounded corners). All told, it's a blockier shape than you'll find on Lenovo's consumer laptops, many of which have been chiseled to resemble a physical book.
We already hinted at this, but the thing that makes the ThinkPad Yoga so special -- that Lift 'n' Lock keyboard -- is also the thing that makes it so heavy. At 3.52 pounds and 0.76 inch thick, it's noticeably heavier than the new Yoga 2 Pro, which comes in at 3.06 pounds/0.61 inch. It's even bulkier than the last-gen Yoga 13, which weighed in at 3.3 pounds and measured 0.67 inch thick.
Even without that newfangled keyboard, the Yoga had a sturdy hinge. Which makes sense, given how much bending the thing was supposed to withstand. With the ThinkPad version, that hinge grew even bigger, as it has to support not just the folding screen, but also a series of mechanisms that help lift the platform between the keys, and then lock the buttons in place. Though the impact on the weight and thickness might not be such a good thing, a bigger hinge at least means the machine handles well. As on the other Yogas, the screen here folds back in one fluid motion, without ever feeling too loosey-goosey. Though the hinge never feels rigid, per se, you will encounter what we'd call a speed bump -- a little bit of resistance to remind you that you've officially entered tablet mode.
And what of that novelty keyboard? As promised, the Lift 'n' Lock system clamps the buttons into place, meaning you can't depress them when the machine is in tablet mode. That's not to say you can't still feel the individual buttons: They're definitely there, and it's easy to tell one from the other just by running your hands over the back of the tablet. Even so, it's definitely a less awkward setup than on the original Yoga, where you can feel the loose buttons on the back. But is it a more elegant solution than what Sony is offering with the Flip series? Or what Toshiba has planned for its 5-in-1 convertible? It's hard to say, particularly with regards to the Toshiba, which isn't even out yet. But it's a question worth asking as you consider buying the ThinkPad Yoga, a machine that's heavier (and no less compromised) than most.
If nothing else, it does seem to us that the self-flattening keyboard would be at home on a smaller, perhaps 11-inch Yoga. Even under the best of circumstances, a nearly 13-inch tablet would be a bit unwieldy, but this one is especially cumbersome, just given how heavy it is. All of which creates something of a catch-22: It's heavy because of that Lift 'n' Lock keyboard, but due to that heft, we're less likely to use the ThinkPad Yoga as a standalone tablet.
Fortunately, there are other poses for you to choose from, including regular laptop mode, "Stand" mode (screen facing away with the keyboard tucked under) and "Tent" mode, with the laptop standing in an upside-down "V" shape. We've always been a fan of Stand mode for watching movies in cramped coach seats, but Tent is well-suited for presentations and videos as well. Interestingly, though Lenovo added a rubber bumper to the Yoga 2 Pro, there's no such gasketing here. That leaves the ThinkPad Yoga's edges exposed when you stand it on its head in Tent mode, but so far, at least, we haven't observed any damage on our review unit.
Finishing up our tour, the ThinkPad Yoga doesn't bring many surprises in the way of ports. For a power adapter, you've got the same OneLink connector found on all new ThinkPads, which has a similar shape to a common USB port. Speaking of the sort, this thing has two USB 3.0 ports -- one on each side -- along with a mini-HDMI socket, headphone jack, SD reader, lock slot and a volume rocker/screen-orientation button to use in tablet mode. There's also a slot for the active pen, located on the right side, toward the front where the palm rest is.
Keyboard and trackpad
Lenovo may have messed with the X1 Carbon's keyboard, adding an adaptive panel with controls that change depending on the app you're using, but in the case of the ThinkPad Yoga, the company's design team didn't take any chances. This is the same spill-resistant, island-style layout we've seen on the last few generations of ThinkPads, with six rows of U-shaped "Smile" keys and a large, buttonless trackpad sitting underneath. Lining the top, you'll see a row of function keys that serve primarily as multimedia controls (read: You'll need to hold down the Fn button to use it for something else). Throughout, the buttons are generously sized, with only a handful of keys (the arrows, PrtSc) that appear shrunken-down. Like other ThinkPads, too, there's a good deal of travel here and the buttons are backed up by a sturdy panel that doesn't bend or flex as you're pecking away. And we'd expect nothing less, really: Given how thick this machine is, relatively speaking, there'd be no excuse not to have dense, cushy keys.
We'll admit: We were initially skeptical when Lenovo said it was moving toward buttonless trackpads for its ThinkPad line. After all, there's something so inherently tactile about the ThinkPad experience: those pillowy keys; the rubber TrackPoint that other companies have tried (and failed) to imitate. Truly, though, the glass touchpad here is easy to use, and Lenovo has refined it so that the learning curve is even smaller than it was last year. When we tested the ThinkPad Helix, for example, we initially encountered a dead zone in the middle of the touchpad -- a no man's land between the regular left/right click buttons and the two buttons up top, which are meant to be used with the TrackPoint. Now, though, Lenovo has painted thin red lines where the two upper touch zones are, so that you don't even have to feel your way around; you'll know from the beginning where your finger is supposed to go.
As before, there's also a row of raised dots right below the TrackPoint, indicating the scroll zone. Beyond that, the touchpad is also easy to press, and it makes a low-pitched sound -- not unlike the keyboard itself, which also makes minimal noise. Gestures work well, too, so much so that you can pinch to zoom very slowly, allowing the font to scale up and down in small increments (because nobody likes going straight from 10-point lettering to 72-point).
Display and sound
Unlike the Yoga 2 Pro, which comes standard with a 3,200 x 1,800 screen, the ThinkPad Yoga starts with a 1,366 x 768 Gorilla Glass panel, though you can upgrade to a 1,920 x 1,080 display for an extra 250 bucks. (Our review unit had the 1080p screen.) Setting the resolution aside, what we like most is the matte, anti-glare finish, which makes it easy to view the screen from any angle, whether it be from off to the side, with the lid dipped forward or with the machine lying face-up in tablet mode. As an added bonus, the screen also appears to be coated in some sort of finish that makes it feel slightly less slick, so that there's just the littlest bit of resistance as you swipe your finger across it (that's a good thing, in case you couldn't tell).
That textured finish also seems to assist with pen input, creating a more paper-like canvas on which to take notes and draw mustaches on people. Even without that matte screen, though, pen input would still be quite good, thanks to the Wacom active digitizer inside. As you might expect, pen input is pressure-sensitive, so your markings will run the gamut from fine lines to thick smudges, depending on how hard you press (and what writing implement you choose). That would be the case with any active digitizer, really, though Wacom's tend to be particularly sensitive to differences in pressure. The one used here also picks up on even the faintest swipes, so we never had to press harder than we would with a normal fountain pen. And, in case you needed a reminder, most competing convertibles don't support pressure-sensitive pen input at all, so if that's a key spec for you, well, this is very good news indeed: Your only option happens to be a very good one.
Unfortunately, with as much care as Lenovo put into the display and writing experience, the speaker setup feels like an afterthought. Like, even more so than on other Ultrabooks. The volume is loud, fortunately, but at almost any sound level, the audio is hollow. Distorted. It'll do in a pinch, but if you're using this on the road, you'll be glad to have access to a set of Bluetooth speakers once you get back home (that's assuming you don't have room in your road warrior bag for a Mini Jambox or some such).
Performance and battery life
The unit we tested has basically the same specs as every other Ultrabook we've reviewed recently -- namely, a 1.6GHz Intel Core i5-4200U CPU, integrated Intel HD 4400 graphics, 4GB of RAM and a 128GB solid-state drive. Even the SSD appears to be the same Samsung-made one used in other ultraportable laptops, which means that in addition to every other benchmark we ran, the read and write speeds are basically identical. In this case, that means 555 MB/s reads and 139 MB/s writes, both of which are normal for SSDs that don't use the PCI Express standard.
In real-world use, the only area where the ThinkPad Yoga seems faster than other Haswell machines is in its boot-up time: The machine takes just seven seconds to get to the login screen, which is even quicker than we're used to. Otherwise, the machine multitasks and launches apps with the best of them, with a strong 802.11ac WiFi connection that performed reliably on various networks (even my home router, which can be sort of poky sometimes). That's all well and good, but it's worth noting that the Yoga 2 Pro offers the same specs for a lower starting price of $999 (versus $1,299 for the ThinkPad Yoga with the same processor and upgraded screen). So as you're shopping around, consider that you can get equal performance at a lower price, even within Lenovo's own lineup. Just be prepared to give up the pressure-sensitive pen input if you decide to go that route.
Lenovo claims up to eight hours on the ThinkPad Yoga, which is pretty spot-on: Our review unit lasted through seven hours and 32 minutes of continuous video playback with WiFi on and the screen fixed at 65 percent brightness. Though it pains us to say it, that's actually fairly short battery life, at least compared to other modern day Ultrabooks. To be fair, it outlasts the skinnier Yoga 2 Pro by about an hour, but even then, its endurance isn't any better than the Acer Aspire S7's -- and that guy's thinner than them all. Considering some Haswell laptops are capable of lasting nine or 10 hours, we expected a little more here, especially since the ThinkPad Yoga is heftier than most other machines in its class.
Software and warranty
As always with the ThinkPad line, you'll find very little third-party software pre-installed, though Lenovo does tend to throw in a bunch of its own programs. These include Live Tiles for Lenovo Settings and Support, as well as one for QuickCast, an app that lets you share files between two ThinkPads. In order for that to work, though, both machines must have the app open, and be connected over the same WiFi connection, so it's mainly useful in offices where the IT guys have issued ThinkPads all around. Meanwhile, Lenovo Reach is the company's own cloud service. For that, by the way, you don't necessarily need a ThinkPad: you can use it on computers, tablets and phones, none of which necessarily has to be made by Lenovo.
As for those third-party apps, the selection is, again, quite small. On board, we have Skitch Touch, Evernote Touch, AccuWeather.com, Kindle, Zinio's magazine store, eBay and the streaming service rara.com. And that's it -- could be much worse. As for warranty coverage, you're looking at a one-year plan, extendable to up to five years.
Configuration options and the competition
The ThinkPad Yoga starts at $999 with a Core i3 processor, 4GB of RAM and a 128GB SSD. From there, you can add a Core i5 or i7 processor, up to 256GB of storage ($150) and, of course, that 1080p screen for an extra $250.
As we've already hinted, the ThinkPad Yoga has some competition from within Lenovo's own lineup. On the off-chance you find the whole convertible thing overrated, the newly refreshed X1 Carbon offers a higher-res 2,560 x 1,440 screen option, and weighs much less (around three pounds with a touchscreen). That said, for $1,299 and up, you're giving up that versatile, shape-shifting design, and won't get the active digitizer, either.
It's a similar story with the Yoga 2 Pro, Lenovo's flagship consumer Ultrabook. It starts at $1,199 (currently on sale for $999) with a 3,200 x 1,800 screen and the same Core i5 processor used in our ThinkPad Yoga test machine. All told, then, it has a sharper screen with a thinner, lighter design and similar performance (minus about an hour of battery life). Still, the lack of pen input is likely to put off some would-be buyers.
Whatever you do, we suggest you stay away from the ThinkPad Helix, if only because it's still running 2012-era Ivy Bridge processors. It's a shame, because in every other respect, this is the ThinkPad Yoga's closest corollary: It has a 12-inch screen that detaches from the keyboard dock, and can be inserted with the screen either facing the keyboard or facing outward. Oh, and it supports pen input too, for a change.
Otherwise, we're left with a mishmash of laptops that fall into one of two categories: business Ultrabooks that don't bend and contort the way the Yoga does, and consumer models intended for a totally different audience. On the business side, you might want to check out the Dell Latitude 7000 series, available in 12- and 14-inch screen sizes, whereas HP, meanwhile, just announced the 14-inch EliteBook Folio 1040 G1. That machine doesn't support pen input. None of these do, actually. In case you were wondering.
As for consumer models, our reigning favorites are the Samsung ATIV 9 Plus, the Acer Aspire S7, the Sony VAIO Pro 13 and the Dell XPS 12. Of the bunch, incidentally, only the XPS 12 has a convertible design (in fairness, it does many of the same things as the Yoga series, just not pen input). Sony also has the convertible Flip series -- and believe it or not, these do support pen input -- though we'd stick to the smaller sizes, if possible (read: the 11- and 13-inch models).
The ThinkPad Yoga's self-flattening keyboard is a neat idea. We'd just rather see it on a machine that was smaller and lighter. As is, the so-called Lift 'n' Lock system comes with a massive catch-22: It makes the entire laptop thicker and heavier, and therefore more cumbersome to use in tablet mode. Which... sort of defeats the purpose of having a laptop that's more comfortable to hold as a standalone slate.
In the meantime, though, we're still inclined to recommend the ThinkPad Yoga, if only because this is one of the only Ultrabooks we know of (business or otherwise) that allows for pen input. And what a nice experience it is, too: The Wacom digitizer allows for nuanced pressure sensitivity, while the display's matte finish makes for some wide viewing angles. The screen is more pleasant to touch as well, thanks to that slightly textured coating.
All told, you can easily find Ultrabooks that offer sharper screens, longer battery life and comparable performance -- sometimes for about the same price. If pen input is important, though, the ThinkPad Yoga is by far your best option, and lucky for you, it also happens to be a solid performer in its own right.
