I think what he means is that average computers today are so overrun by
spyware and trojans that giving them a non-repudiatable way of
authenticating transactions is actually a big risk to the user.

I've certainly heard this from banks in the UK. They are developing
portable smart card readers where users have to type numbers into the
machine from the screen and type numbers back into the computer from the
reader, just so they can have a secure platform for authenticating
transactions. They are bypassing the client entirely.

This, of course, is a usability nightmare. :-(
