You've been able to subscribe your calendar to your salesforce.com events for ages now. Well, OK, for almost two weeks now. But that's old news. Starting today (about 3 minutes ago, in fact) you can also subscribe to your tasks, or as iCal likes to call them, TODOs.
Just subscribe to this calendar with your iCal-enabled PIM (only Apple iCal has been tested so far), log in with your salesforce.com username and password, set it to refresh periodically (not more than once an hour, please), and make sure to uncheck the Remove To-Do Items option.
Remember, you must be a Spanning Salesforce user to access this service.
