Hi Hermelin,
Don't know if anyone's mentioned this as I've not read every post here, but the OVF has an optional miniature live view display showing in the bottom right corner. Not only does this show exactly what the EVF would, but it can be altered to display only the precise area of focus of the OVF, rather than the whole scene. This isn't intrusive, as it sits where the view would be obscured by the lens anyway. And, as I said, if you find it distracting you can switch it off.
And there's more: this mini EVF is responsive to exposure compensation changes, just like the LCD or main EVF would be. So it's a neat alternative to using the histogram as you can see how bright or dark the scene is with your chosen exposure settings.
Another benefit is using it really saves on battery use.
I love the OVF, primarily for street photography. It's very useful when your waiting for someone to come into the scene. Being able to see them in the viewfinder whilst they're still outside the framing lines helps you click at the right moment. It also gives the impression that you're actually interested in something else besides your target subject whilst they walk into the frame lines. And in setting like that the subjects are rarely so close that super precise framing is required. But I would agree that there's really no functional point in going the X Pro route if you don't want or like the OVF. Yes, it's specs are better than any other Fuji, but only for now.
