Wait for the "but"...This was quite possibly the best laptop I have ever used, even as a network admin for over a decade I've never found a laptop so well balanced with speed and functionality. I loaded Battlefront II and other video games with no lag on the highest settings. The touch-sensitive display is beautiful and the wacom pen works better on this screen than on the Wacom Cintiq (which had about a 1/2mm offset in the corners. It's the perfect PC for gaming, artists, video editing and more.But there is a terrible defect on all of the Yoga's with the 4k UHD screen. The infamous black bar that drops down between the UHD screen layers. This started after a few days of owning it. I discovered that this will be the case with every one of this model and Lenovo has no plans to fix it because quite simply there is no way to fix it without replacing the entire screen! This tells you that Lenovo intentionally pushed a faulty product knowing that every single one was going to fail. Turning the laptop upside down and shaking it made the black bar fall back into its correct position helped the first time but the black film just dropped down again after another week. Wehn I returned it I noticed that they had another on display with the same problem. If you want a great laptop with a black bar going right through the screen then this is the perfect PC for you! I hate to say it but this would have been the best PC for the price on the market without the defect. I would have gladly paid an extra $1,000.00 just to have the great design and functionality of this laptop WITHOUT the defect but there's no way around it, if you use the laptop, you WILL have this problem. PS. The other 720 models to date really cannot compare at all. Such a great graphics PC and such a waste due to bad R&D. It broke my heart to return the laptop. I ended up buying an MSI gaming laptop that cost twice as much and has half of the features but at least it doesn't have defects.
