Don't own one but have seen a few pass through Copenhagen workshops over the years. They are quite heavy. Looks are of course a matter of taste.
Steer clear of the 2 cheaper ones (single speed has NASTY component choice and Nexus hubbed one is ... well ... a Nexus-hubbed one.)
Not seen an MN1 though but spec looks good.
To be brutally honest though - the place I have seen most of them - is as never-ridden office decoration for overpaid Copenhagen designers and architects when I was a bike messenger.
but somehow i made me really want to know more about the bike.
I just found the pricelist and with that i lost my interest , way overpriced even for a Marc Newson design
