I’ve used Gmail/Calendar, and have just migrated my data back to iCal, since now I have a laptop it makes a bit more sense to have the data stored locally.
There is one thing I’d like to see possible in both systems is to mark a meeting attendee as attending. It only appears to be possible to do this from the person themselves. Sometimes I speak to an attendee of a function, and they are coming, but the email or calendar system they are using does not integrate well with iCal/gCal, so the email is sent back, and I need to modify stuff manually.
Google Calendar at least allows you to add “Guests”, something I haven’t yet figured out how to do with iCal.
However, with iCal, it appears to be possible to script iCal, so I may be able to add this functionality.
Not to mention that the invitations do not show up for lots of people.
Not sure what they see, might need to do some testing.
