According to the iPod Fan blog:
The iPod is so well known in its two distinctive colors (white and black), that we hardly imagine they coming in other colors. But now, thanks to Target, you can get a really colorful iPod. Target is selling the Pink iPod, which is officially called the ColorAware iPod, Pink edition. Different models are coming in this color, including the iPod video (figure above), and the iPod nano.
We still don't know if this is exclusive to Target, neither if other colors will be made available, but it is really nice.
