Much better. I'm still going to be inclined to copy some of W7's icons over to 10 though I think.
Old and New.... I like the less-flat look, a little more color to catch the eye. Trash bin looks like the old one from XP and appears to be transparent. The nav arrows upper left are visible, where before they were hard to see. The whole nav panel looks much nicer (I do have mine expanded, though). Ribbon icons are brighter, sharper, and easier to see and interpret.
File folders are file folders... but nice to see first couple of items in each folder for quick ID.
All in all, it looks much cleaner and easier on the eyes.
