*Space grey doesn't look as expensive and good as slate black. *5S camera flash too bright in some pictures compared to the 5. *Finger print sensor not quite as response was I thought. *Slow motion is good but don't see why the 5 couldn't do this? *The interesting one userablity wise the speed is not much faster so far. Especially in Safari it's like for like. Old games load no quicker. So of you have an iphone 5 fear not you are not missing much and still have the latest iphone (5C) just in last years metal case. 5S is not as big an update as you might expect.
