Well, I use it, I like it, and I can confidently say it's not for everyone

You gotta think the gnome way. Like, for example, I don't feel the absence of the minimize button because I adopted gnome's workspace-based flow

It doesn't get in my way, I don't even feel its existence most of the time. Gnome 3 sucked and definitely got in my way but beware that I am talking about gnome 4x here.
