The two new iPhone 5S colors are striking as well, I expected the space gray option to just be a renamed black option from the 5, but it actually has different aluminum anodization and looks like a different color around the edge and back metal parts. Of course there's a dramatic change with the gold colored iPhone 5S, which actually is quite subtle in person and not nearly as dramatic as I thought it would be. It manages to be gold but still elegant and not tacky, I'm impressed with the way Apple tuned this anodization. The materials feel the same as they did on the 5, which is to say excellent.
