Close. Syncing between two Macs doesn’t work quite right, as part of a .Mac workflow. You can save your data to an iDisk or a USB stick, but the two different iGTDs don’t mesh up when it comes to syncing with iCal (which syncs through .Mac already). It doesn’t see that an item on iCal that got there through iCal syncing is the same item in iGTD if that particual instance of iGTD didn’t put it there. You end up with duplicate calendars, etc. Maybe there’s a way to go about it, but frankly for now I am going to stick to an iCal-only solution.
