Totally agree, access to a phone calendar is needed. Since Samsung programmers can't do their job properly, it takes more than several minutes on my 3GHz system to synchronize several kilobytes of contacts/calendar, so I would prefer to use AirDroid to make fast changes in the phone and than sync with Outlook in the evening.
Google would be convenient, but it is not an option since I don't want Google to read/process my personal information.
