The only memory we have left of it is the zune desktop software. I really love everything about it. The fact of using very subtle gradients, awesome animations, an original UI, a few drop shadows, and those awesome changing color gradients... Sure, the current mui (modern ui) is way better than google's material design, or apple's yosemite design, but I wish win9 will go back to the roots of metro. Seriously, can you imagine an entire OS that looks as amazing as zune did?
