Either because there are > more possible parts with slightly different size or the specifications I guess different device batches have different revisions of the internal MMC chip. This is quite normal, since the manufacturer constantly improves their designed/fixes bugs in the MMC controller on the chip etc. During this process stuff gets modified (e.g. the scrap space used for error correction). So if the difference is little this is the explanation. On this matter. Are there any inside pictures from the N810 yet? Collin -- Collin R.
