I wasn't to sure either, but I just went with my preferred regular Pandora color. I never really liked the black color much, and when the platinum was announced, I like that even less. But once I got my 1Ghz unit, I really found the platinum to be the way to go. I went with the grey, and I think it's a solid choice.I was about $15 short, so I'm waiting till next check. I'm not exactly sure between the two colors yet either.
