Driver issues were very minimal (had to turn off a power management thing, and use the on board graphics card for most usage), maybe an hour-ish. Otherwise, I was completely shocked how modern the experience is. Honestly, I find it better than the Mac UI because it lets me just get shit done without getting in my way. Keyboard shortcuts are weird, but I was using Windows 10 in the mix as well, so I'm used to that. However, I was never big into the apple ecosystem, so it would be more painful if you have an iphone, ipad, use itunes for everything, etc.

I'm in the google ecosystem, so life was crazy easy.
