Outlook 2007 has to-do items: they're not tasks but potentially any kind of item (email, calendar, contact, etc) that has been flagged for follow-up. These items can be assigned due-date, reminders, etc. I've been searching to see if I can find out any technical information on how these items are differentiated in Outlook from regular items, but if there was a way to be about to sync these to-do items with Toodledo, that would be amazing.
I've just started using Toodledo with Outlook Sync, and it's fantastic. Thanks for your hard work - it's making my life so much easier.
