The video card is a little lightweight for gaming, but the notebook itself is powerful and has a lot of great features.  The display is nothing short of amazing.  If you have eagle-eyes like me and love tiny dots, you can't beat 4K on a 15" screen!  The screen real estate on this is magnificent, but it defaults to 150% font size, so if you really want to cram lots of info & Windows on it, cut the screen fonts to 100%.There is one significant drawback.  The 15" Yoga 720 will *NOT* charge via USB-C.  The 13" will, but NOT the 15".  I use a Pluggable USB-C Docking station to provide signal to external monitor (4K!), Gigabit Ethernet, and a USB-3 webcam.  Since it won't charge on USB-C, I also have to plug in the power adapter.  Frustrating that I have to buy another power brick for travel, but it wouldn't stop me from buying the unit.
