I actually love the different colours The iPhone 5c sports the same 4.0-inch 640x1136 seen in the iPhone 5 and the iPhone 5s.
Yes, that display feels small in a world full of Android flagships around the 5.0-inch mark, and other even bigger devices that push the definition of the words phone and, indeed the bastardisation that is phablet.
While the likes of Nokia and BlackBerry have realised the importance of having large screen offerings in the form of the Lumia 1520 and the BlackBerry Z30 respectively, Apple, rather obstinately some believe, continues to hold out. It is expected Apple will change that by finally releasing a bigger iPhone in 2014, though of course theres nothing even remotely official about that statement. Until then, if you want the iOS experience, you can choose between the 3.5-inch screen of the iPhone 4S or the 4.0-inch display that iPhone 5c and iPhone 5s offer.
