I’m kind of sorry that the SmartCard never caught on, and not just because it’s the only way to upgrade the firmware on the Motif ES (which probably won’t be getting any more firmware upgrades now that the XS has been released). I recently found the one that I borrowed indefinitely for the aforementioned purpose in the bottom of the washing machine as I was transferring clothes to the dryer. I just reformatted it and it seems to be working fine.
