I have been using Things, but wanted to try OmniFocus. I like what I see in OF so far, but got stopped dead when I saw that OF could not see my Exchange calendar. (I'm using Snow Leopard, btw. Snow Leopard has been out since August 28, 2009)

That calendar can't be "read only" since Things works just fine with it. Maybe Things is using some kind of AppleEvent hook with iCal. I know it's pretty easy to write an AppleScript that creates iCal events in that Exchange calendar, because I've done it. It's puzzling that OF for Mac can't do something similar to Things.

At this point, the lack of integration with Exchange is a deal killer. The promise of Version 2.0 is nice, but we've been waiting a long time already.
