What is the purpose of a hinged
EVF as opposed to a hinged OVF (assuming a hinged VF is even possible - perhaps substitute interchangeable)?
The hinged OVF is restricted to a specific alignment, like 90 deg. determined at the design stage. The optical view must be translated in a specific direction to end up in the view finder.
On the other hand, a hinged EVF translates a video signal down a wire that can be twisted in whatever direction that a ball joint can show a screen.
But even a hinged EVF, not cheap by the way, i think they can run $400 or more. But take a look at the picture below of my Nex6 broadcasting a signal to the android phone next to it:

The wonderful thing about EVF, is now the signal can be easily broadcast, on the camera's own WIFI network to a smart phone like device. The smart phone need not be hooked up to an internet wifi but detects the camera's own local network of up to 150' in a recent test i did on my Nex6 using an android smart phone.
But coming down to what should be on the camera and what should be left to a camera's wifi network, i think a hinged or articulated LCD combined with a fixed EVF works great. clip on EVFs are expensive and tend to snag on lots of things as one tries to carry them or put them in bags. In most cases, hinged LCDs combined with a fixed EVF on camera, like the Nex6 fits any needs. Ultimately, a smart phone carrys any needs beyond that point to a smart phone which can be used on a camera at floor level on a sunny day or up to 100 to 150' feet away.
Frankly, a hinged OVF is "so yesteryear". Once a camera is outfitted for wifi uploading and establishing its own WIFI, like the recent Sony Nex family and Fuji's, its a simple step to use one's smart phone as an EVF. (Just looked it up on Dpreview, this is what Fuji's Feature report says for the XTI model:
Built-in Wi-Fi including remote control from a smartphone or tablet
Wifi, EVF, tethering, remote operation, are all in the same soup together if designed that way. There was a report that someone was getting dizzy from EVF - sounds to me like the refresh rate was not adequate on the camera. Mirrorless and smart phones are leaping ahead of traditional DSLRs with their capabilities. My Sony Nex6 did not come with remote operation but required me to download a free app from Sony and install it on the camera and on my smart phone. Once installed, it takes about 15 sec or less to get both devices turned on to the app. Even though my Nex6 does not allow a touch screen, my remote android phone allows me to set a new focus point remotely using touch on the smart phone screen.
