Thanks - I'd already posted there, but apart from a few sample photos, there's not much in the way of information. Shouldn't be long before the full reviews come out though.
I share your interest Ade - had a feel in Jessops today and it is indeed very small (the camera!). I thought the Nikon 3100 was dinky till I saw it. Actually the Nikon feels more ergonomic in the hand but for sheer "smallness" the Pentax is fantastic. £299 is a good price - where from?
