I've searched, but can't find a similar thread. So, other than the obviouis physical differences, what little things have you found to be different between the S and X? Two-wheel-press reboot blanks and possibly reboots both screens in the X while only rebooting the center screen in the S. (X reboots in about 1/4 the time of the S, but is likely the difference in computer speeds.) Charge port is always lit when plugged in on the X while the S shuts off after a short bit. One additional level of suspension adjustment in the X, now defaults to low vs standard in the S. I know there were a few more things I've run across, but can't recall at the moment. I'll keep adding to the list as we identify them.
