I purchased the UHD Y50 for 4K video editing. It's a great laptop that boots in about a second, and it plays 4K video with little to no stuttering. The only downsides are that while the display is beautiful, the color yellow is noticeably dark and brownish (and apparently the only model without a touchscreen), the touchpad is finicky, but easily overcome by using a mouse, and it is as wide as a standard 17" laptop, though still comparatively slim and light. Also note worthy, the JBL speakers are quite impressive compared to other laptop speakers. Great bang for the buck if you price match. Outperforms some gaming desktops at lower cost considering perepherials.
