For those interested in the relative weight of the Kindles I have weighed my PW1 and the wifes PW2 both of which are fitted with the official Amazon cases. Only differnce is the colour, one pink (not mine

) one black.
PW1 = 342g
PW2 = 343g
Be interesting to see what the weight of the Voyager + Oragami (leather and fabric) case is.
