Lenovo yoga 900 The Lenovo Yoga 900 keeps the slim watchband-style hinge from last year's version, and adds major upgrades to performance and battery life. Even the lowest-cost version includes a big 256GB SSD. Dispplay It has a bright, super-sharp multi-touch display, with a resolution of 3200 x 1800 pixels ("QHD+"). It has a thick bezel running along the bottom, giving it a 16 x 9 aspect ratio, which is great for watching video but makes just about everything else a little awkward. Position another 13-inch laptop next to the Yoga — whether it’s a MacBook (16:10) or the new Surface Book (3:2) — and the Yoga’s display will look slightly compressed in comparison. The Yoga 900 weighs 2.8 pounds and measures 0.59 by 12.75 by 8.96 inches. All of the standard ports are there, with the addition of a USB Type-C port. It is slightly heavier and thicker than last year’s Yoga 3 Pro laptop. But it never felt heavy to carry around. And when you consider the new stuff included in this one, it’s forgivable.
That "stuff" includes Intel’s sixth-generation Core i5 or i7 Skylake processor, a new chip touted for its speed, efficiency and graphics support; along with an Intel HD Graphics 520 GPU. The previous Yoga model got dinged for slowness; that wasn’t my experience with this one. In everyday use, the Yoga 900 was more than capable of running multiple apps, switching between tasks, and streaming video without any stutters. The Yoga 900’s battery life is definitely improved over last year’s Yoga 3 Pro, but compared to other laptops in this class, it’s still not the best. In a Verge battery test, the Lenovo Yoga 900 lived up to the company’s claim of nine hours. During a more normal day of use, running multiple apps, checking email, and browsing the web with some battery-saving settings turned on, it was inconsistent. Some days it lasted around five and a half hours, and other days closer to seven and a half. In either instance it doesn’t match the new Surface Book or recent MacBook Pro models. Performance
This is where the 900 really does the job. As mentioned previously, the review model I was using was the top-end version of the 900 series. As you'd expect, Windows 10 ran perfectly smoothly in both Tablet and Desktop mode, with programs loading extremely quickly and no sign of any slowdown or crashes.
Whether or not you have the super-boss level version of the Yoga 900, with the new i5 and i7 processors backed up by SSDs and at least 8GB of RAM in each model, this device is sufficiently equipped to deal with pretty much anything you throw at it – short of hardcore gaming.
In terms of exact configurations, you can choose between the Intel Core i5-6200U or i7-6500U processors, 8GB of RAM – which can be upgrade to 16GB – and either a 256GB or 512GB SSD.
The integrated Intel HD Graphics 520 also does enough for the average user. The 900 scored fairly well on the PCMark 8 test, clocking in at 2,403. This puts it ever so slightly ahead of the Surface Pro 4’s 2,396 and somewhat behind the Dell XPS 13 Skylake’s 2,543.
In the Geekbench multi-core scores, the 900 beat both the Surface Pro 4 and theXPS 13. While the 900 had a score of 6,786, the Surface came in at 6,727 and the XPS at 6,242.
In 3DMark: Fire Strike test, the 900 scored a respectable 834. This puts it in the range of the Surface Pro and XPS 13 (Skylake), with scores of 853 and 838 respectively. And in the Cloud Gate test it came in at 5,860, behind the Surface Pro with 6,109 and the above the XPS 13 with 5,844.
Essentially, you won’t notice much difference between the Yoga 900 and similar Ultrabooks. The device is more than capable of handling most tasks, but it obviously isn't a gamer’s dream in terms of graphical performance.
But,Because of the change to more powerful processors, the body adds a little thickness. A few keys on the keyboard suffer from awkward placement.
THE BOTTOM LINE Lenovo clearly listened to feedback about last year's high-end Yoga, keeping the excellent overall design but boosting the specs to match other premium 13-inch laptops. Specifications

Price :$1199.00VS Apple MacBook Pro with Retina Display (13-inch,2015) The 13-inch MacBook Pro with Retina Display adds the Force Touch trackpad from the new MacBook as well as fifth generation Intel processors, Intel Iris Graphics 6100 graphics, and up to 10 hours of battery life.Apple adds new Intel CPUs, faster memory, longer battery life and its new Force Touch trackpad to the standard 13-inch MacBook Pro, which keeps its generous selection of ports. When compared to last year’s 13-inch Retina MacBook Pro, the new models are only 7 percent faster than the older laptops they respectively replace. In order to see gains over 10 percent, you have to compare the new laptop to models released in 2013.
The graphics improvement is much more impressive: The new 13-inch Retina MacBook Pro had a 29 percent increase over last year’s models in the Cinebench OpenGL tests. It’s not the 40 percent that Apple touts, but Apple’s testing was done with a different benchmark that includes three video games.
In the Black Magic Disk Speed Test, the 13-inch Retina MacBook Pro posted an average write speed of 1156.1 MBps and an average read speed of 1299.9 MBps. The 13-inch Macbook Pro hasn't had a radical redesign, and its shape, dimensions, weight and port configurations are identical to the outgoing model. That means two Thunderbolt 2 ports, a USB 3.0 port, a headphone jack and a MagSafe 2 port on the left, and a second USB 3.0 port, SDXC card slot and HDMI 1.4 port on the right. The screen resolution is 2,560 x 1,600 pixels, but you actually get the screen real-estate of a 1,280 x 800 pixel-resolution display due to the pixel-doubled effect that provides Retina-like sharpness. Apps like SwitchResX allow you to access even higher resolutions than OS X allows, stretching all the way up to 3,360 x 2,100.
Text is too tiny to be legible at that setting, but opting for one in-between, such as 1,920 x 1,200, lets you fit much more of spreadsheets and other apps into the display than any of the default screen resolutions at the expensive of clarity.
but,The 2015 updates make only a minor difference to the hands-on experience, while similar high-end 13-inch laptops continue to get thinner and lighter.THE BOTTOM LINE While the upcoming 12-inch MacBook has all the buzz, this 13-inch system gets a handful of updates to remain a top choice for combining power and portability.
