The Hitachi with the cover is not even FOPS rated. The legs on the outside are set to the catwalks which are welded into the side of the curve on the house frame. It's better than nothing and does convey a sense of security to the operator. It will stop small trees and maybe a one man rock falling from a high wall.
As far as the window goes, AtlasRob is correct about the window breaking hammer. All Hitachi excavators came with them from the Dash Five up. Komatsu put zippers in the molding around the rear windows. I think Cat does the same.
I've seen many a log come through the front window and not even slow down. I've also seen machine accidents that were fatal where big trees have flattened the guard, cab and actually bent the bottom of the house frame.
The big thing for me is having qualified operators. The proper move to make before that flip over would have been to swing the bucket down the hill using the bucket to act as a leg.
