Should I Upgrade My iPhone 4 to a 5c?

Verizon is offering a free upgrade and I don't know if it has a lot of problems or anything. I looked up the 5c and found out it has a stupid plastic case -.

It does have a plastic case. My personal opinion is to purchase the 5S even though it costs more, it is worth every extra feature, better camera, better processer card, just an overall better performance. Plus you don't have to worry about breaking it on it's first drop.

Wait for the 6, its coming out soon.
