I think you're right, though it's an opinion that's not going to be popular around here until these things are everywhere by this time next year. These are very 80s colors and the 80s are in style again. I see numerous women wearing day-glo orange tops lately. The colors that Apple is using on these iPhone 5Cs is a more muted, subtle take on that, but it's definitely a nod in that direction. I think the 5C is going to be a huge hit with younger people, and not just because of the price.Like it or not, Apple is a trend setter in the world of design.
Look for pastel (and champagne) colors to suddenly become fashionable and cool over the next few months/years.
