I am currently using google calendar/gmail as my core calendar and email applications. For off-line use I have synchronized these with Mozilla's Thunderbird w/lightning plug-in. I like Sandy but would like to sync it with these other apps so there is one master calendar, task list, alerts. Sandy would be the app which notifies me and how would often get updates into the system (e.g., "remind me of ..."). As an aside I have Jott synchronized to google calendar which is cool -- it would be nicer to synch Jott to Sandy.
