It looks very nice indeed. After the success of the Olympus Pen I think we're going to be seeing a lot of this style of camera which is a great thing for those of us that want something small but with a lot of control.
I rarely take my DSLR underground any more as the bulk is just a pain. The pictures from my Panasonic LX3 are nearly as good and it's just so much nicer to take underground.
