Análisis para el Lenovo IdeaPad Yoga 13
Split Personality. With full 360-degree hinges and touchscreen capabilities, the Yoga series is perhaps Lenovo’s most ambitious addition to the IdeaPad family to date. Its launch and hardware were designed to coincide with the release of Windows 8, generating even more word-of-mouth. Is this $999 hybrid Ultrabook a one trick pony? Or is it a novel concept with a promising future?

Disponible en formato de 11" con Windows RT y con pantalla de 13", ya con la versión completa de Windows 8. Esta última configuración es la que hemos analizado, y el sabor de boca que nos ha dejado es estupendo, tanto por lo atractivo de su carcasa (muy agradable al tacto y robusta), como por su comportamiento general.

La Yoga 13 es mi ultrabook favorita hasta ahora. Quizás no funcione bien como una tablet, pero como dispositivo de trabajo, incluso de entretenimiento, gracias a las transformaciones que puede hacer, la hacen sumamente versátil. Pero más que eso, es la calidad del teclado, trackpad y pantalla, que son sumamente cómodos como para trabajar a gusto. Recomendada.

Se puede encontrar ordenadores y tabletas de características parecidas a precios más bajos, pero lo modelos que integran ambas cosas tienen un precio similar. Algunos consumidores preferirán disponer por una parte de un portátil y por otra de una tableta, dándoles un uso diferente, pero siempre hay quien gusta de llevar todo en el mismo equipo. Como casi todo en la vida, es una cuestión de gustos.

It's official, the Lenovo IdeaPad Yoga 13 is a completely different beast than the Yoga 11. This one has a great screen and sound quality of the type we'd like to see more often on ultrabooks. With good battery life and a lightweight body, the Yoga 13 is a prime choice for people on the go.

Wer mit die vielen verschiedenen Einsatzzwecke, die ich im Video beschrieben habe, benötigt wird mit dem Ultrabook sicherlich zurechtkommen. Aber: Man sollte sich auch darauf einlassen, man entdeckt nämlich meist erst bei der Nutzung welchen Modus man benötigt und welcher überflüssig ist. Ich jedenfalls habe den Tablet-Modus am meisten geschätzt und am häufigsten genutzt.

Lenovo has included some added extras that allegedly make using Windows 8 easier. One of these, Motion Control, meant we could wave at the laptop to get it to perform basic tasks. By using the webcam the laptop could skip music tracks or move between photos when we waved a hand at it. Clever, but it has limited uses at present.

Like most of the Windows 8 convertible tablet/laptops we’ve looked at, the Lenovo IdeaPad Yoga 13 isn’t quite the perfect hybrid. However, if you regard it as a touch-screen Ultrabook with a cool twist, it certainly succeeds. It’s generally well-built, looks stylish and feels great, and its flexible hinge gives you lots of different usage scenarios. While no match for the ThinkPad range, its keyboard is pleasant enough to type on and its touchpad is lovely, while that 1,600 x 900 IPS screen supports 10-finger touch. It also has plenty of power under the hood, and backs this with decent battery life. If a more affordable Core i3/i5 version becomes available in the UK, it’ll be a steal.

The Yoga 13 has a rather enthralling design, mostly because of the dexterous design. It remains very thin as an ultrabook, and the ability to sustain various Yoga positions makes it useful in various usage scenarios otherwise unimagined till now. Ever thought your ultrabook could sit with you on the counter, displaying the recipe while you cook? Exactly my point. Excellent battery life makes it even more of a value for money proposition. The keyboard is quite disappointing though, not in terms of the key response and consistency, but for the dip when you type. All things considered, the Yoga 13 is a slightly better deal than the Dell XPS 12 convertible.

In our review of the Yoga 11 we felt that too much cash was being asked for what amounted to too little in return. Enter the IdeaPad Yoga 13, however, and it tackles these issues head on: it's got more power and, importantly, runs the full version of Windows 8, so it can do much more. Overall there are more-powerful options out there, but the Yoga 13 does succeed in delivering enough power in a striking and luxury body. It's the build element that elevates the score, despite the noted expense which may be enough to cause some prospective buyers to look elsewhere.

It’s been a lot of fun to review the Yoga 13 but our concerns about the weight and usability have been confirmed. A 13” tablet could be useful for gaming and business but we see the Yoga 13 not quite reaching the full potential when used as a tablet. Certainly for some tablet users the digitizer component is missing. For consumers, it’s heavy.

As what I primarily do is writing and programming, having a good keyboard is critical for me, which is why a tablet alone can’t work for me, and when I started looking I needed at least a tablet/keyboard dock hybrid. The Yoga caught my eye for being an actual laptop with a touchscreen integrated, but the hinging allowing it to be used entirely as a tablet. I did a lot of scrutinizing of the machine on display in Best Buy before I finally purchased it to make sure it fit my needs.

Making a usable Windows 8 hybrid is all about compromise, and Lenovo has managed to get the balance just about right. The double-jointed hinge balances flexibility with durability, performance is good and the IPS display is simply glorious. Rather than making an overweight tablet with crippled laptop features, Lenovo has created a solid, attractive Ultrabook that doubles as an occasional, king-sized 13.3in tablet. It still isn’t perfect, but for £1,000, the Yoga 13 is the first hybrid Windows 8 device worth shelling out for.

Overall, I think Lenovo has shown that a convertible notebook can be a viable option in today’s market, especially for someone that is still on the fence about wanting a tablet but still requiring a notebook for productivity purposes. You can expect to pay a slight premium considering the hardware that’s included but that’s also expected given the flexibility and hybrid nature of the system.

The bottom line is that the Yoga 13 is a powerful, full-featured Ultrabook but the 360-degree hinge design might be as much of a design flaw as it is a unique selling point. If you want a laptop that converts into a tablet without the exposed keyboard then there are other options like the Dell XPS 12 or Lenovo's own ThinkPad Twist. If you like the various screen positons of the Yoga 13 and don't mind the exposed keyboard then this is a fabulous Windows 8 PC.

The Lenovo Yoga is an excellent laptop, a mediocre tablet, and a computer that is thoroughly modern and made for Windows 8. Its form factor and excellent screen make it a competitor at its price range against last generation’s top laptops and ultrabooks, such as the Asus Zenbook or Thinkpad X1. If you never flip the Yoga into tablet mode, it’s a great laptop, and if you do, it’s a little bit of bonus functionality that doesn’t hurt the form factor that much. At $1000, which is its MSRP price, it’s certainly a competitor, but as this form factor and set of guts starts to edge down price-wise after the holiday season, the Yoga becomes an easy laptop to recommend.

The Lenovo IdeaPad Yoga is aptly named - it's flexible in more than one way. Not only can this Ultrabook be used as a laptop and a tablet, its screen can actually swivel around the hinge 360 degrees to maximize the tablet experience. It is quite big and heavy at 16.9mm and 1.47kg to use a handheld tablet for any length of time but that's the nature of a hybrid device like this. And it's a pretty cool device when you consider that, oh yeah, it's both a laptop and a tablet.

In our real world testing, the system was a pleasure to use. Not only was it responsive, but the keyboard and touchpad were very comfortable to use as well. In addition, the muti-touch display was quick to respond to our demands and we found it to be useful in all configurations—tablet, stand, tent, and even laptop mode.

I’ll admit it – at first I was a bit skeptical of the Yoga as a concept. In theory, it seems like an Ultrabook-slash-tablet is doomed to be mediocre at best. But the Yoga is surprisingly awesome. Sure, it’s not going to replace your iPad, but for a laptop it does the tablet thing very well (and it does the laptop thing pretty well, too). It helps that the keyboard, trackpad, and touchscreen are all top-notch – the Yoga is so eminently usable that I barely care what its performance scores are.

The Lenovo IdeaPad Yoga 13 is a very good ultrabook, and with a price tag of $999, it offers a lot—a reasonable feature set, touch screen, and good design. If you just want a great ultrabook, the Yoga 13 is good, but the Editors' Choice Toshiba Portege Z935-P300 $799.99 at Amazon Marketplace is better, with similar specs and performance, but lighter, thinner construction and a lower price. As a hybrid ultrabook, however, the Yoga 13 has a versatile touch screen, a flexible design, and the best laptop-to-tablet transition mechanics we've yet seen in a hybrid. It's good enough that we hope other manufacturers adopt similar designs, but at a better size—the Yoga 13 is just a little too big for comfortable use as a tablet. If you are shopping for a Windows 8 ultrabook laptop with touch capability and plan on only using the tablet mode occasionally, then the Yoga 13 is a smart choice; but the Dell XPS 12 is better as a tablet.

The Lenovo Yoga is a very smart move for the company, and is a device that certainly gives us a preview of the hybrid laptop/tablet devices that are going to invade the market in the coming months. As a laptop the Yoga performs well, but as a tablet the device just seems a bit too big to use comfortably. The responsiveness of the screen could also be fine-tuned a bit to make the Windows 8 experience absolutely perfect. While the Yoga does have a few strikes against it, it’s nevertheless a sturdy and capable device that is perfect for anyone who wants the best of both the laptop and tablet world.

Back in January, when we first saw the Lenovo IdeaPad Yoga at CES, we declared it to be one of the most memorable things to come out of the show. That was 10 months ago, though, and thanks to that gap, there's a bit of a discrepancy between our initial impressions and our reaction following a week of real-world use.

The Lenovo IdeaPad Yoga 13 is one of the more eye-catching convertible tablets to commemorate Windows 8's launch. It has all the features we like from the IdeaPad U line (slimness, a classy chassis and very good keyboard) paired with a sharp and bright 1600 x 900 IPS touch screen. The Yoga is quick and responsive thanks to the SSD drive and Windows 8's spritely performance.

Overall this is a thoughtful and very usable hybrid, with an abundance of both little touches, like a motion-control system that works via the webcam, and big ones, like the keyboard automatically disabling when the Yoga’s in slate mode. While I’m not sure that anyone really wants a tablet that’s quite this big, at the very least it’s a solid contender for the laptop user who just wants the occasional touchscreen experience available.

The IdeaPad Yoga is an able contortionist, blurring the line between laptop and tablet, while enabling users to explore the full capabilities of Windows 8. The soft-touch design, comfortable keyboard and swift performance also impresss. Those willing to spend $200 more may prefer the Dell XPS 12, which sports a brighter and higher-res 1080p screen and whose design makes it easier to switch from notebook to tablet mode.

The Lenovo IdeaPad Yoga is a good Ultrabook for the price, even without some of the fancier features. The design, display, and performance are enough to capture our attention. But the touchscreen and versatile convertibility put it over the top. The Yoga showcases everything that Windows 8 has to offer. Plus, the $999 price feels like a bargain when you take all the features and specs into consideration.

Those prices may be a little difficult to swallow, but I think if you have a bit of extra cash you’re willing to part with, you probably won’t be disappointed with the Yoga 13.

The biggest hardware trend marking the launch of Windows 8 is the proliferation of touch-screen laptop/tablet hybrids. Some have screens that pull apart to become separate tablets, while others have screens that flip, twist, or rotate to give you a tabletlike shape to hold. The Lenovo IdeaPad Yoga 13 is a convertible touch-screen laptop/tablet that most importantly doesn't compromise the traditional laptop experience.

Because all Windows 8 Ultrabooks share the same specification - at press time, every Ultrabook featured the same base processor - hardware and design will be the differentiating factor for the next half year, and possibly longer. That means aesthetics, batteries, input device, and other intangibles will matter more than anything else. With the hyper-flexible Yoga, Lenovo has the most, or at least the first, meaningful intangible. For now, it's hard to imagine anyone topping a device that can be favorably compared to other laptops as well as tablet convertibles.

Lenovo's IdeaPad Yoga 13 is a solid Windows 8 based ultrabook laptop with a fantastic keyboard and multitouch display that also has the added benefit of being used as a tablet. Although awkward to hold as a tablet because of its size and the exposed but disabled keyboard, it is a nice capability to have especially when you want to watch a movie or just browse the web.

The big question for us though, is whether anyone actually needs something like this? The answer is probably yes, but it's not going to be hugely mass market. As pretty and well built as it is, a separate laptop/tablet solution might be more convenient for those planning to make their work/play ratio the more fun side of 70/30.
