When the first generation Zune 30 was released November 14th, 2006 there two limited run Zune colors: Magenta Pink and Day-glow Orange. Each of these colors were limited to 500 made. Many of these went out as a gift to the members of the Zune team. From what I understand the Pink was for the US and the Orange
was for Europe (Actually Jessica, just pinged me and told me that they were both US and the Zune Team got to choose which color they wanted). After gifting these Zunes the remaining were randomly inserted into retail channels.
I picked up the Pink Zune when it was first released back in 2006 from eBay- the Orange Zune I just picked up from @chrisleckness nearly completing the ship gift Zune. I think the only one that remains is the Zune 16 Citron- a yellow Zune that popped up when the first flash Zunes were released. The only person I know who has one is Co-host of ZuneInsider Podcast, Matt Akers and he refuses to sell. Anyone up for a covert mission to infiltrate his office at Zune headquarters? In the meantime, enjoy the photo shoot of these two limited edition Zunes.
