But how do you do that when you have so little screen space? Do you sacrifice content for UI?
My biggest complaint about the direction UI have been moving is that EVERYTHING is being shifted to this concept. My desktop monitor is the size of a small television, you don't need to hide everything in tiny drop-down menus. Because designers are trying to make all interfaces the same they are working to the smallest denominator (phone screen) instead of optimizing interfaces for their intended usage.
There are never any bugs you haven't found yet.
