All of which is true.  However, the bit to which I was replying was:

"A smartcard is very convenient as far as it's a multi application
device, so you can store much other info apart from GnuPG keys, i.e.
Mozilla passwords or such."

... And I'm still trying to figure out how that's different from a flash
drive.  Maybe there is a difference and I'm not seeing it.  Or maybe
there isn't one.
