Compared to something like the Galaxy S5 or LG G3, the iPhone 5S is miles ahead when it comes to design, although less so than the HTC One M9 or One Mini 2 which have repeated the aluminium-clad trick.
But beyond that I'm still impressed with the design of the iPhone 5S. It's hard not to be, as if there's one thing that Apple gets totally right it's the way it assembles its devices.
The metal and glass combination does feel a little fragile, and I'd recommend a case (perhaps a third-party option) to protect the aluminium, but the design is something that at least helps mitigate the higher price.
You can always use headphones, but that kind of negates the point of the speakers for gaming completely.
Battery life could be better
Touch ID works perfectly
