How do you guys keep your laptops synced with your main computer? I know dot mac offers this capability but I want something a little cheaper (I'm a college student). I've looked at SyncTogether but think its a little buggy / I want something a little more automatic (you have to launch the program to sync). I've also tried spanning sync and busy sync but while I like them they only do ical (I want at least being able to sync my address book). Are there any more good programs out there? Thanks!
