Wired just published a nice article on secure computing:

Wired: Signs of 'Trustworthy Computing'

NEC Computing International has announced a trial program in which Packard Bell PCs will be equipped with keyboards that include secure smart-card readers.
Ok .. Packard Bell is not known for good computers, but it's a start towards more security in the computing field ...

Although it could also be a risk if the lazy user leaves his smart-card around after using it .... but that's a whole other discussion.

Cheers,
