Comparision :iPhone 5C and 5S versus older iPhone 5......Worth to invest on??

iPhone 5C and 5S versus older iPhone 5
Apple's new iPhone 5S and 5C and last year's iPhone 5 are alike in many ways. All three phones have a touch screen measuring 4 inches (10 centimeters) diagonally, with a resolution of 326 pixels per inch. That pixel density is better than Apple's iPads, though not as good as Samsung's flagship Galaxy S4.  

The iPhone 5 and 5S are identical in size and weight, while the 5C is slightly bigger and heavier. The iPhone 5S is identical in price to what the iPhone 5 cost when it was introduced last year, while the 5C is $100 cheaper.

Battery life is comparable. Talk time is boosted on the 5C and 5S, as is Internet use over LTE cellular connections. Video playback and Internet use over Wi-Fi remain the same. Like all previous models, the battery on the new phones can be replaced only by service personnel.

Main differences

The main differences: The 5S has a fingerprint sensor, a better camera and a faster processor, while the 5C comes in five colors and uses plastic instead of aluminum and glass for its casing.
