I took the original images to try to figure out the dimensions. Just drew a line on the diagonal of the screen, divided the length of said line by 6 for a pixel per inch figure. Then drew lines on the length and width of the device and divided them by the ppi from the screen. Assuming its a 6" screen (and this seems most likely) here is what I came up with:
width 5.301886792"
height 7.962264151"
So rounding we've got 5.3x8". I'm not going to try it again with the high res images because I'm fairly certain we'd end up with the same numbers. I'd love to figure out the depth, but I can not for the life of me find the diameter of a pencil on Google.
Oh wow, just noticed this is my first post since joining in June!
