Hell, I would be happy just to get iPhone's Mail app to be able to click on an ".ics" calendar event. Seriously, how hard is this? iPhone syncs my calendars, iPhone syncs my mail, iPhone's Calendar app views all my already imported ics files. Why can't it just open up an .ics calendar attachment? Plus, they were promising this way back in 3.0. Forget, iWork, give me a "working" calendar!
+1, oh, and display week numbers in the Calendar too
If iWork comes to iPhone then it would need to be 100% compatible with the iPad version with no exceptions.
I wonder if the iBooks wireless syncing (via your iTunes account) is the first step in an enhanced cloud strategy?
