I'm an advocate of SPF, but not because it's the magic bullet that stops spam. It does however allow innocent domains to say "no, I didn't send that" and thus avoid the double-bounced backwash from a spammer forging their domain as the sender.
Envelope "cookie" schemes on outbound email, like SRS, can achieve that, far better (*you* know whether the bounce is legit, rather than relying on the bouncer to do the checking) and without the collateral damage of SPF.
