I think it is time for new or different smartphone designs (a couple of examples: http://www.androidauthority.com/samsung-sm-g9198-flip-634219/ and http://www.theverge.com/2015/8/13/9147239/samsung-keyboard-case-note-5-s6-edge-plus).
In particular I think it would be cool to see removable keyboard, secondary screens, integrated covers with keyboards, external batteries, speakers, cameras, docking stations, etc.
The MS Surface is a good example of what can be done with a laptop/tablet (even if I think we only scratched the surface with what can be done - pun not intended), the same should apply to smartphones.
