Re: WTF?
Perhaps its a personal preference thing but I can't see a rear screen as well as I can see through a view finder, and that's not just because I need my reading glasses to work properly with the rear screen. I've got a D300 and in lots of lighting situations I can't see enough on the rear screen to be able to compose properly let alone focus. On a sunny day there just isn't enough light coming out. Now I've never used one of these, so perhaps they've got a much brighter screen, but I've never seen any display on anything that can compete with sunlight and not blind you (except ePaper and that isn't going to work for a camera).
I've not replaced my late lamented Cannon S60 for the reason they've stopped giving a real viewfinder as an option on the new models.
