I have a Tilt / Kaiser that I've been syncing with my Mac at work for about a year. I have somewhat restricted access to installing a lot of apps on this Mac, as it is my work computer, so I am not up for installing updates and new versions every few weeks. I just want to install a sync program and have it work consistently. Currently I am using Syncmate for this. It's good, but has issues fairly regularly with things getting "corrupted" which require me to delete all of my contacts or calendar from the phone, and resync completely from the Mac. Has anyone used BOTH syncmate and missing sync, that could offer opinions on which they prefer? Thanks for the help!
