An awesome review by Rene Ritchie at iMore. Worth the read if you don't want to go full iPhone 5s or just love great writing.
The iPhone 5c, it turns out, wasn't a pure budget play at all. It's play was pure pop.
The 2013 iPhone 5c may sport mostly 2012 iPhone 5 guts, and it may sit in that same $100 off slot, but the first time, it's a first-class member of the product lineup.
I'll admit it, I like the iPhone 5c more than I thought I would. After using it non-stop last weekend, I missed it when I switched to the iPhone 5s. I missed its color. I missed its feel. The iPhone 5s screams premium, all gorgeously metallic and scorchingly fast. But the iPhone 5c really is fun. When I put it down, that's what I missed. And when I switched back to it on alternate days, that's what I enjoyed.
