Are there any other options rather than waiting until the 650 comes out???

Meetingmaker conduits for palm, that works with either palm desktop or with missing sync.

I have seen something that will allow meetingmaker to convert over to iCal, but then there is no way to sync back from iCal to MM.

Is there any other way to sync both ways from a Mac to a PDA with Meetingmaker, or am I just out of luck until the Treo 650 finally arrives? I want bluetooth, and this seems to be the only option...
