The more I use the X-S10, the more I use the fully articulated screen (FAS) in ways that are unique to this little gizmo. I find I am far more likely to try different POV in my shots, and this has proved to be productive, at least to me. I have always liked the tilt LCD for waist level/lower angle shots, but I've expanded this far more with the FAS. I've had FAS before, but never seemed to take advantage of them. Of course, some form of stabilization is more important since I am often holding the camera in strange ways. I could mimic much of this by changing my body position, but I find as I get older I am less willing to kneel/lie down/wallow on/in the ground/mud/snow/puddle. It would be interesting to try a wearable EVF as a further extension of this capability. Of course, there has been some dabbling in this area, including the US military in the Land Warrior system:
This is hard for casual shooting since it makes you look like a Borg, but for a day of dedicated shooting it would be useful and it is well within the boundaries of current technology. Of course, the usual disclaimers about type of photography, etc., apply.
