Lenovo ThinkPad X1 Yoga The 14" ThinkPad X1 Yoga is supremely thin yet rigid, and it has a spill resistant keyboard-- it's ready for the road and isn't in the least bit delicate. It weighs 2.8 pounds (1.27 Kg), and Lenovo claims it's the lightest and thinnest 14" business portable. weighing in at just 2.8 lbs. It's not quite as light as the waiflike Lenovo ThinkPad X1 Carbon, which weighs just 2.6 lbs., but it is noticeably lighter than the 3-lb. MacBook Air, even though that machine has a smaller, 13-inch display. That makes the X1 Yoga a better option for commuters and frequent travelers who need a notebook that's easy to lug around. The definition of versatility, this ultralight 2-in-1 adapts to your business with 4 flexible modes to work, present, create, and connect. Features a stunning display with intense color and deep contrast. Even a dockable, rechargeable stylus pen. Plus, the fastest, advanced mobile broadband technology available. The ThinkPad X1 Yoga will be the first laptop to offer this technology when it hits the market in spring of 2016, and believe me – it’s incredible. Lenovo will also build an X1 Yoga with a standard display, and showed it side-by-side with the OLED model. I could see the difference even from across the room. The OLED panel’s superior contrast made dark backgrounds look far deeper and, just as importantly, helped fine details stand out. It is the first convertible device being launched with an OLED (Organic Light Emitting Diode) display. We’ve seen these displays predominately on smartphones, with the occasional tablet as well, but it’s now made its way to the laptop form factor. Lenovo is using a Samsung OLED as the optional panel, and it’s a 14-inch 2560x1440 version. Samsung is the market leader in OLED technology, so it makes a lot of sense that they would turn to them for this display. The base device comes with a 1920x1080 IPS LCD, and there is also an optional 2560x1440 IPS LCD too, but the OLED should give a large gamut and of course the deep blacks that OLED is known for, along with infinite contrast. It is exciting to see that this technology is now making its way here. The other big change, as the name of the ThinkPad X1 Yoga indicates, is that the keyboard of Lenovo’s flagship business ultraportable now flips around 360 degrees. So, you can use it in laptop mode, tent mode (like an inverted V), stand mode and as an absolutely enormous tablet. The keys retract into the base for this last mode, to make the rear feel flatter in the hand. The laptop has a 4 cell, 52 Whr battery that's sealed inside. You could replace it if you remove the bottom cover affixed with several Phillips head screws. Lenovo claims 11 hour runtimes (9 for the OLED display model), and as ever that's optimistic. We did however average 9 hours of productivity and streaming video use with brightness set to 40% (a bit dim for my taste) and WiFi on. That's quite good for a very slim and light laptop with a 14" full HD display and the Core i7 CPU. It supports Lenovo's quick charge, so a half hour layover at the airport can significantly top up the battery.The full-sized, backlit keyboard is spill-resistant and the keys retract automatically when not being used as a laptop, so they are not exposed when the keyboard is face-down on a desk or table. The ThinkPad X1 Yoga runs on 6th generation Intel Skylake dual core, 15 watt core i5 and i7 CPUs with SSD drives, and your choice of 1920 x 1080 x QHD 2560 x 1440 IPS touch screens with pen input.

VS Microsoft Surface Pro 4
There's a new reigning king of Windows tablets and its name is the Surface Pro 4. Building on everything the last iteration got right, this new slate introduces a larger screen more sensitive touchscreen perfected for everything from penning documents to painting images. Thanks to a newly redesigned island keyboard, tapping away on the Type Cover feels almost as good as a real laptop and the glass trackpad feels simply superb. Internally the Microsoft's latest also features a faster processor and storage, all in a shell that's actually lighter and thinner than the Surface Pro 3. Overall, these improvements make the Surface Pro 4 an affordable Windows tablet that really can replace your laptop.The Surface Pro 4 fits a larger screen with a higher resolution into a slightly slimmer body than last year's model. The pen and keyboard cover are also improved, and this is one of the first mobile systems shipping with Intel's latest processors. Design The Surface tablet line set out its basic design rules with the very first generation of products and has largely stuck to its guns since. What we've seen, instead of wholesale reimagining, is a steady march of improvements to the display and chassis, helping the product feel just a bit more premium with every generation.
The earliest Surface Pro models were 13mm thick, while last year's Surface Pro 3 shaved that down to 9.1mm. This year, we're down to 8.4mm, despite increasing the size of the screen. Both the Surface Pro 3 and Surface Pro 4 are 1.7 pounds (771 grams) by themselves, or 2.5 pounds (1.13 kg) with their keyboard cover and stylus pens attached. One of the biggest improvements to last year's Surface Pro carries over here: the highly adjustable kickstand, which can be adjusted to nearly any angle between 22 and 150 degrees. The kickstand, which runs the entire width of the system, is stiff enough that it will stay where you put it, and hardly moves at all, even when using your fingers or the pen on the touchscreen.
Missing from the black bezel surrounding the screen this time around is the capacitive Windows logo touch button. In previous Surface models, this moved around from the long edge to the short edge of the system, but always served the same purpose: to take you back to the Windows 8 tile interface. As we're now operating in the Windows 10 world, having a physical home button isn't necessary, although the Windows 10 "tablet mode" is still very similar to what Window 8 looked like. Performance Microsoft is offering the Surface Pro 4 in sixth-generation Intel Core M, Core i5 and Core i7 options. The M version comes with Intel HD graphics 515, while the i5 comes with slightly more powerful Intel HD graphics 520. The top i7 variant comes with Intel HD graphics 540. Adding further complexity to the mix, you can also load the Pro 4 with 4GB, 8GB or 16GB of RAM. I tested the Core i5 model with 8GB of RAM.
The model benchmarked fairly well. The Surface Pro 4 ran in with a 6,727 multi-core Geekbench score. On the graphics intensive 3DMark: Cloud Gate, it scored a solid 6,019. Neither scores are groundbreaking, but they put the Pro 4 on a par with most top-end 2015 convertible tablets and well above its 2014 predecessor. By comparison, the Surface Pro 3 scored 3,491 in Geekbench.
The benchmarks proved accurate with real-world use, and the Surface Pro 4 delivers solidly impressive performance. Using the unit as my primary tablet and laptop, I didn’t notice any serious performance jitters. The Surface loaded web pages instantly, ran applications smoothly, and proved capable of playing Steam games, such as Deathwatch: Tyranid Invasion and Divinity Original Sin, chug free – if the graphics settings weren't maxed.
Battery life Microsoft touts a battery life of up to nine hours of video playback – that's the same figure given for the Pro 3 so there's no official benefit on this front. We're still testing batter life and will add our results very soon. But,Microsoft still refuses to include the Type Cover keyboard by default, forcing a separate purchase. Battery life still isn't enough for a full day. The Bottom Line A host of small refinements cements the Surface Pro 4's position as the best-in-class Windows tablet -- so long as you're prepared to pay extra for the required keyboard cover accessory.
