Great review and lovely images, thanks! I wonder about a couple of things: do you think the camera is a little, well, overpriced? Around £30 would seem fairer to me, without the paper and film.
Also, those shots look sharp! I've seen a lot of Zero pics on Flickr, but none look as beautifully sharp and free of distortion and vignetting as this, even accounting for screen shrinkage. This throws me into a quandry, as I was thinking seriously of coughing up for a Zero. Is there any chance that you might perhaps post something a bit larger?
