iCal is supa fly
Apple: iCal -- Jaguar users, download it now! It is, da bomb. :-)
It's not as good for business/project/customer tracking as Marketcircle's DayLite, but that's DayLite's focus, and not iCal's.
I'll forgive Apple for not having Canadian holiday and NHL schedule calendars in their Calendar Library, 'cause iCal rocks, but please make one sooooon! (feedback already sent to iCal team) Update: I have it from a friend of a friend of a friend who works in the iApps group that a Canadian holiday schedule is forthcoming. :-)
BTW, I want to make a WeblogView page that generates an iCal file so people can subscribe to the blog in iCal, but I don't think Conversant has all the things I need to do it. :-( (hint hint) It would be a nice groupware feature, wouldn't it?
