I am hopefully going to be getting an iPhone 5 OR 5c for my bday in December. I like the colorful look and feel of the 5c and I am leaning towards getting it over the 5. But are there any significant differences between the 5 and the 5c? I know the specs are pretty much identical, but is there any important difference to make me choose one over the other? Or is it just the design? I will have a case on it all the time, so I figure that the 5's aluminum design wont make much difference if it has a thin, plastic case on it versus the 5c with the Apple case on it. For people who use cases, is there a big design difference between the 5 and 5c besides the color?
