I have found the articulated screens great for getting worm-eye view. self taking a group or couples photo, easier to see in the sun because you can tilt the screen until the sun isn't making a glare, and shooting overhead of a crowd. I've never had one on a DSLR and don't really miss it because the viewfinder is so much better than using the LCD screen. I could probably have used an articulating screen in less than 1% of the shots with the DSLR.
Have you guys been in situations where a articulated or flip out LCD display on a camera was useful? What kinds of shots/situations were they?
Is this a feature I should consider when buying a DSLR?
