I have never seen an ad in windows in my entire life on any of my machines. Apparently it is the first thing I disable when I open up the settings on a new install. It's gotten to the point that I'm almost curious about it. Ubuntu has the amazon integration which bothers me about just as much.
Ubuntu tried to pull some weird netbook phone hybrid that didn't work well on any type of device. 8 years we had to live with Unity.
I'd say that the UI of Windows 10 is about ten years ahead of anything in the linux world (and I doubt linux well ever be as polished). I say that as someone who is possibly going to do the switch to linux this year, but I'm in for a rough transition.
