What these UX morons, and a lot of posters here as well, seem to forget is that the title bar of a window already has a purpose. It is meant to be a clear visual cue that a window exists and be a place where one may quickly and easily grab the window to move it. We should not have to find the one place on the title bar that allows this. This is fundamental to how an operating system with windows works. Chrome is a major offender in this area too.
It might be fantastic for grandma to be able to have the search bar be so prominent on the one application she has permanently open on her netbook, but for someone like me who has multiple explorer windows, browsers, IDEs, messaging apps and countless other windows open at the same time, any hindrance to quickly and easily putting those windows in place for a given daily activity is a loss of productivity and a distraction from my actual goal.
We know that MS will ignore this feedback and forge onwards making their software more and more painful to use. I just hope that one day in the future, as the company fades into obscurity, another company looks at things like this as a case study and sees forums like this as a cautionary tale of how to piss off your users for no reason other than to satisfy the ego of some brat who just finished their UX training and is needing to validate their existence.
