I'd take that with a nice shoe-mounted optical finder (and ideally DoF/hyperfocal markings on the lens). I think it looks fantastic, but may require a new line of slim lenses to fit the shape. Don't want to end up like this: http://www.cameraquest.com/nrf1000.htm

I'm also starting to think that with all Pentax's p*nc*ke (

) lenses (15mm, 21mm, 40mm, 70mm and even the 35mm at a push) they could be in the ideal position to make something very similar to this Olympus mockup.
