Mine has been really solid. I use it for work and side projects right now.
Switching video cards has been my biggest issue. The Nvidia sucks battery so there are times I want to switch to the integrated Intel. The switch works, but switching back hangs the machine. It happens in the logout or shutdown part of switching video and the login (MDM on mint) never loads. It doesn't matter which card I switch to or from, just the second swap every time. Mint 18.2 is using LightDM which I'm hoping will work better, but I haven't tried yet.
