This is one of my favorite laptops, Lenovo really has done everything it could to make this stylish laptop convertible good. The overall design of this laptop is very good, at 2.8 pounds, it is a little bit heavier than the Lenovo Yoga 3 Pro (2.6 LB) it makes up for that in processing power. You see, when the Lenovo Yoga 3 Pro was first introduced, it ran on an Intel Core M processor, making it slim but also decreasing the processor power. The Lenovo Yoga 900 runs on a Intel Core i7 6500 Skylake processer . However, the Lenovo Yoga Pro 3 ran on a Core M 1.1 GHZ processor, making it way less functional than even a Core i3. The design is pretty much the same as the Pro 3 but the watchband design did change. The OS is Windows 10 Home, but you can upgrade to Windows 10 Pro via a USB (There is no CD Rom, as one would expect from a slim laptop. The storage is what you would expect for a 1,200$ laptop, 256 GB on starting model. It can be upgraded to 512 GB if you buy a more expensive model. The resolution comes in a non-matte 3200 x 1800. The other competitors are : Apple MacBook Air, Surface Pro 4, Surface book, HP Spectre, Dell XPS 13, and Toshiba Satellite radius 12 (With a 4K display, but more on that later.) Overall rating : 8.75 Out of 10.
