But also no real advantage, IMO. Mounting an adapter is not that much trouble ...[/quote]
If you (1) don't switch lenses often -and- (2) don't switch lenses in a hurry -and- (3) don't care about compact size when the camera is off with the lens attached, then yes, I agree that a collapsing (folding) lens mount has no advantage over a detachable adapter.

How do you want to do something as slim as an Oly pen with the 17mm with the senor to mound distance of the Nikon F?[/quote]
That depends on what type of lens you connect - legacy (e.g. regular F-mount) or new (e.g. F-mount, but optics designed for short register distance)
When you use a legacy lens, the mount is folded when the camera is turned off and overall depth of the body is similar to the PEN. When you turn the camera on, the mount expands to the correct register distance (it's obviously deeper in this mode).
When you use a new lens, the mount remains folded regardless of whether the camera is on or off.
Added bonus #1: When you use a new lens and want to shoot macro, just flick a switch and the mount expands like using a built in extension tube.
Added bonus #2: When you use an old MF lens, the lens mount expansion/folding mechanism can double as a moving platform to implement AF.
Now you'll probably say that all this is impossible to engineer, too expensive, too heavy, too slow, too unreliable, too ugly and so on, right? That's the way of naysayers I guess...
