Everyone's trying to convert 8.x into 7, instead of just installing 7. It's hard to understand people sometimes...
This is like a breath of fresh air. That new Explorer was just not so easy on the eyes, very distracting. Thanks for posting this.
I hated the bottom details pane and absolutely love the new side pane (I have 1920 horizontal pixels, so this makes very good use of that). I also never liked the useless old drive grouping. And who ever used the command bar? Keyboard shortcuts for common tasks, menu for advanced things. The ribbon makes accessing those advanced features much faster than the old menu-digging. Ah, to each their own, I guess.
So why bother even saying so? I have a large screen bigger than 1920 but still hated the new layout in 8.0/8.1, I prefer it at bottom.
