Pixel per inch on SJ30

[kennyd]

Anyone no what the pixel per inch on a SJ30 is.  By measuring the screan at 2.125" and 320x320 I came up with 150 pixel/per inch.  Is this figure actually documented somewhere.  Interepreting the edge of the screan is ambiguous to me, and was just wondering if anyone knew for sure what the pixel/inch was.
