I really have to have a desktop calendar that works on my computer when I'm offline, and that syncs with my phone when I leave the office. I use Macs at home and work. I know the Droid is set up to use Google Calendar, but that doesn't sync well with iCal (you can sync only one way, from Google to iCal, but not in reverse). So that's not an option for me. Is there some other calendar program that will sync smoothly between the Droid and my desktop? (I'm not married to iCal, I just need something that works on a Mac.) This is kind of a deal-breaker for me -- I'll have to return my Droid if I can't use a calendar (and my 30-day clock is ticking!). But it seems so basic, I'm sure there must be a solution. Has anybody solved this problem?
