hardware.  The separation of devices is the advantage, as a compromised
laptop generating it's own 2fa is questionable- but some of the soft tokens
will run on phones or other devices (which are, of course, targets of
attack themselves).

If you want to play with software 2fa, you might want to check out WiKID (
wikidsystems.com), they have an Open Source version so you can play for
free.
