The Zune HD has been kick’n it for a few months on retail shelves. But if you’re planning on buying one sometime soon and purple and magenta are your colors, you might want to wait until December 1st. On that day the portable will be available in those lovely colors in addition to the five that are already available. Of course you can customize your Zune HD even more with the signature Zune Original Artwork and through the holiday’s, free engraving. [via Gizmodo]
