FaceTime camera seems useless. What the watch really needs is way faster internals and the capability of doing most tasks by itself. In it's current state, glances and apps take way too long to load. The whole design of the 'home screen' needs to be changed as well, it's far too unintuitive to launch apps the way it is.
The physical design shouldn't change too much, IMO. A little thinner would be ok but bands should be compatible.
The Taptic Feedback should be dramatically more powerful. I still find myself missing some notifications even with the highest vibration setting on. The internal speaker needs a big boost, as phone calls besides in private are way too quiet.
TL;DR: Speed, speed, speed
