Source? I've monitored the rankings on Amazon, Best Buy and Circuit City. The Zune 80 has consistently done well but the Zune 4/8 are hurting. Early Feb. Microsoft quietly dropped the Zune 8 price down to $179 but I'm not sure it helped. I wish I had better numbers to draw on but I think what we have access to is good enough to make some generalizations. Don't get me wrong, I want Zune to do very well.
