What do we want? Classic! When do we want it? Now!
I add my voice to the others who prefer Classic.
MS is no less than other organizations infested with people who have to make their mark by changing something, even for the worse. And different people have different desires. Classic for me; Aero/Modern/Fiddledaddle for others.
I like displays that cater to my eyeballs' fovea. Google figured this out. Others here have commented on how multiple clicking interferes with work flow. Right! It's a distraction, seemingly small, but centered at the heart of the user's actions.
