I know people have their preferences for built-in or detachable EVFs, but I've come to really appreciate the detachable kind. Yes, they are bulbous and a bit clumsy to deal with, but being able to swivel it 90 degrees has been immensely useful. I have the new Olympus EP3 and 24mm lens and with that wide a lens I often have it lower down and try to keep it level in both directions. Being able to look straight down into the EVF perfectly facilitates this. To me, swiveling LCDs serve a similar purpose but they are not the same. I still prefer to frame through the VF. I find it to be a more intimate connection to the image (and it helps with stability). Downsides, I cannot use the EVF and external flash at the same time. But it is rare that I ever use flash. Still, an important consideration. The choice of EVF type comes down to personal preference. I'd be curious to hear why others prefer one type or the other.
