I didn't read through all of these but if programs like Things or Easy Task Manager could sync with Toodledo, I'd love it. I've noticed there aren't many robust stand alone apps out there but there are a few that would be cool to sync with.
I know that Toodledo syncs with ical and google cal but are there any stand alone apps like Things or Easy Task Manager that Toodledo syncs with? I really like that ical syncs with my gcal which syncs with my saisuke calendar. I also like Evernote's idea of having a stand alone app, online component, and an iphone app. I just wish there was a good software that synced as well.
