Herman The Stimulator translation: OVF = optical viewfinder; EVF = electronic viewfinder; back screen = LCD on the camera's back.
I'm generally an EVF addict, but I do like my LCD and wish it was a flip up (the X101?), but a good OVF with info. is very handy, too. I am much too much of a diplomat to be an all or nothing voter, Herman.
I find the flip screen on the G1 and Canon Powershot very useful
I find the flip screen more useful that the standard "flat" LCD screen
on my DSLR I prefer the OVF, except when doing tripod work when the use of the LCD in preview and manual focus mode is very good, (useful)
and on the M8 I have no option - so it's OVF and scale focussing
So what I need, Herman, screen and viewfinder wise - is the functionality of the Nikon D300 in a Leica M Body with a swivel Canon or Panasonic LCD screen - but I don't think Mr Leica will accommodate "anytime soon" as you "cross the pond" people say
I've been an OVF guy for a long time. I've been using the EP1, so forced to LCD, with the EP3 I was going to get the EVF, but now with touch-to-shoot on the LCD, this is MUCH easier than a VF, focus and recompose.
