Things I like: reintroducing a little bit of 3D/skeumorphism. I'm sick of flat. Also the Music and Podcasts app changes aren't bad. Haven't tried the iPhone/desktop tighter integration but it looks interesting. Not UI, but it seems like my wifi is faster, but I could also be nuts. Maybe a driver update?

Things that are "meh": the "apps" thing that replaces the previous launch pad, the translucency, the "dark" icon theme.

Things I don't like: stop wasting my f'ing screen real estate. Stop it with the unnecessary whitespace and the f'ing thicc menu bar. This is a desktop/laptop and it's for real work. It's also ugly. Speaking of ugly, I count several different window corner radii. Why do Windows need gigantically rounded corners?
