Thanks for everyone contributing, but it's going to be most helpful to us if folks can describe what they're using calendar sync for. Detail is good.
Examples: when folks say that they use calendar syncing to delegate or share information with other folks on a team, or to see their tasks on a windows machine, that lets us know that we should be looking at supporting those workflows better, so those folks don't need to go through the calendar hack they're currently using. It's better to provide folks with the feature they actually want than a way they can kinda sorta get it. :-)
In general, we
still feel that OmniFocus and calendars track different types of information - we're hoping to get a better understanding of the benefits that folks are seeing when they mix them.
Thanks, everyone!
